Let's see if I can get you up to speed, OP.
Here's a very basic text guide on combat:

Here are two simple video tutorials that goes over the basics of break/topple/daze and chain attacks:

Melia is very different from the other characters, so she takes some extra getting used to. GAF member Zornica made an excellent guide on how to play her in the Xenoblade OT:

Here's a good video guide to compliment Zornica's post:

Speaking of the Xenoblade OT, make sure you check it out! It's not as active as it used to be, but there's still some very helpful people in there who will give you advice:

Some final tips:
-
Agility is the most important stat in the game! It affects your accuracy (crucial when fighting higher level enemies) and your dodge rate.
- Don't ignore gems! Crafting high level gems (especially Agility gems) will make the game
so much easier. NeoGAF member Man God made an
awesome gem crafting tutorial post in the Xenoblade OT.
- Shulk is amazing! Ignore anyone in here who tells you to not use him. Get the hang of his Monado arts and you are a
huge asset to your party:
--
Enchant lets your party members hit Mechon and increases everyone's auto attack damage.
--
Shield blocks an enemy's Talent Art. You can tell if an enemy is using a talent art if you get a vision, and the attack the enemy is using has a roman numeral after its name. Your Monado Shield's level must be equal to or greater than the level of the enemy's Talent Art in order to block it. Talent Arts usually do a ton of damage, so being able to block them is a lifesaver.
--
Speed grants a huge temporary boost to the dodge rate of your targeted party member. If you get a vision of an enemy using an attack with
red font color, use Speed on whoever the enemy is targeting and the attack will most likely miss.
--
Purge is explained pretty well when you acquire it. It shuts down enemy aura & spike abilities. For example, certain monsters have a spike ability where you take damage every time you auto attack them (you'll see purple damage numbers appearing over your party members and your HP will start dropping fast). Use Purge to temporarily nullify this.
-- There are two "hidden" Monado arts that you can acquire though sidequests later in the game. One of them (
Eater) is kinda lame, but the other (
Armor) is probably the most overpowered defensive art in the entire game.
