Fffffffffffff, I have no idea what kind of gear I should be using for my WD/DH.
Ooh, ooh, something I can actually help someone with on here for once!
At very low-to mid MP (which I'm guessing is what you'd be doing with the DH) the standard DH build is going to be a cookie cutter HA/BL build that looks something like this:
http://us.battle.net/d3/en/calculator/demon-hunter#iahgVd!eXZ!acZYcb
I personally would recommend Smokescreen over Tumble, Perfectionist instead of Tactical Advantage, and Sharpshooter over Night Stalker (at least until your crit % hits ~45, then switch to Night Stalker). The build itself is very straightforward, just do BL into masses of enemies and do HA as needed to restore Hatred and/or on single targets. HA/BL is only really effective up until mid-MP, past there the builds change quite a bit but you'd be a ways off from that. Assuming you're not going super seriously into DH-land, the gearing is going to be the same for about any of these builds with one or two exceptions that only matter for specific higher level builds. You want to look for:
Bow - Manticore. Always always this. Inarguably BiS for DH's unless you're running a 1h xbow which is only one specific build at higher MPs. Manticores can also roll 2 sockets, but you can get one socket ones for dirt cheap since they drop often. They always roll at least IAS, CD, socket, you can probably get a cheap one with Dex and maybe Vit.
Quiver - Dead Man's Legacy. Also inarguably BiS. They always roll with one DH skill bonus, don't worry about that, just get one with the best IAS/Dex/Vit you can for your budget.
Helm - At super starter level your best choice is probably an Adariel's Visage. It has the additional fire damage taken problem, but it's dirt cheap and it always rolls 8-9% IAS and 4.5% CD. On the US AH you can get ones with 150+ Dex and a socket for 500k. Stick a Vit gem in the socket if you get one with a socket.
Chest - You have multiple options here, but even at lower levels I would still probably recommend the Nat chest; the 3-set bonus is pretty good, and it rolls Dex, Life %, 3 sockets, a DH skill and a 2(?) random affixes. You can go for a double dex roll + Vit and Max Disc, etc. Some other chests might be a bit tankier but the 3-set bonus on this is good, and if you can I'd highly recommend getting one with Max Disc on it so you don't have to get that on your quiver (Max Disc on a DML reduces the possible stats it can roll).
Belt - Either the Inna belt or a Witching Hour. The Inna belt is a dirt cheap option, and since you're goign to be getting the Inna pants that 2-set dex bonus is nice. The WH is inarguably BiS though and prices have come down considerably. I would see if you could get a cheap WH with Dex and either Vit or AR on it, but if that's just not going to happen then Inna belt is a good short-term option.
Pants - Inna pants, inarguably BiS. Try to get 9% IAS (rolls either 8 or 9) then you can either go for a 100+ Dex roll, or sub-100 Dex with Vit. You can get 100+ Dex and Vit but that will probably be out of your starting budget.
Boots - Nat boots, again BiS here. Don't worry about trying to get Vit, and they always roll with AR and armor. Just get the highest dex you can here to start off. This plus the chest will give you the two set bonus which is +7% CC which is HUGE and a must have!
Shoulders - Craft, or just starting off you can probably get a Dex + Vit Vile Wards cheap.
Gloves - Craft, or if you're buying just go for Dex + CC + CD with some kind of Vit and/or AR in there depending on what you can afford.
Bracers - Craft, or if buying just go for the Dex + Vit/AR + CC you can afford. I'm personally not really a fan of the Lacunis in general, but in this build you're already going to have max MS% anyway so that shouldn't be a factor. Strongarm Bracers may be a good specific option, they always roll CC and Life %.
Ammy - No specific DH ammy really, just go for Dex + Avg Damage + CC + CD as you can afford. eHP (Vit/AR) is a luxury item on jewelry, if you can get it great but don't sacrifice DPS for it.
Rings - Snag a cheap Nat ring; this will give you the 3 set bonus of 130 Dex which at low levels will make up for any other stats you're missing on it. They also always roll 8 or 9% IAS. Getting CC as well is usually much more expensive, but CD might be a doable cheap option. For the other ring just go for whatever with Avg Damage + Dex + CC. For a specific recommendation the Unity is really solid; they're pretty cheap and always roll good avg damage, a primary stat, CC, LoH and elite damage. IAS and CD will probably be out of your price range for the one random roll on them but you could probably get Vit pretty cheap.
Ignore the skill setup, but you can look at my DH
here, except for the helm it's set up in pretty much the exact same way.
This is my DH:

Caveat being I didn't play 1.0.5 onwards and only just now got back to it.
I would highly suggest dropping Breathe Deep on Smokescreen for Lingering Fog (BD is useless) and Battle Scars on Prep for Backup Plan.
Also Steady Aim is largely useless once you hit Inferno MP1+ because there's just no way to kill things fast enough to maintain the distance in most encounters. I'd suggest either Night Stalker (if your CC is ~45% or higher, it makes a much bigger difference than I thought before I tried it) or Perfectionist.
