Hell, I'd settle for finding people to play the tabletop game with. But that seems pretty unlikely.
There are some resources for finding people to game with nearby, depending on where you are. Is you're going to PAX, that as good a place as any.
The good roleplaying groups are always willing to take in new blood. New roleplayers are the best because they often have minimal or no preconceptions as to what they're supposed to be doing, which is great because you should be able to do pretty much whatever you want. New roleplayers also don't have some habits that the older gamers do.
Vampire can be a difficult game to find a suitable group for, some of them can be weirduncomfortably so. If you like the vibe of that game, I'd say have a look at the Kickstarter that just finished called Urban Shadows. It's a different approach to the same kind of world that is more conducive to producing the game at the table that Vampire tries to, but fails.
If I could free up some of my hobby time, I'd be able to prepare a game that I've said I'd run many times. Roleplaying and miniature related stuff that I'm currently participating in is eating up most of it, but that will ease with time.
I've never played any tabletop games. But they all seem so interesting!
If you're extending tabletop to include board games and even miniature games, there are a number of places where you can participate or find other people who would love to have you. Local hobby stores are a great place to start.

but i've read like the sourcebooks for 2 editions of D&D, like 6 versions of WoD/nWoD, and am probably going to end up reading a bunch of Shadowrun sourcebooks at some point
Inexplicably the fiction writing in WoD sourcebooks is far superior to the actual fiction books they publish
I'm beginning to read Dragon Kings by Timothy Brown. It's the spiritual successor to Dark Sun, which he also wrote, and after one chapter I want to know so much more about the world. There seems to be plenty of detail, but leaves enough gaps to be filled during play without being frustrating to read in the slightest. It only just came out in PDF with the hardcover to follow later. Worth every cent in my mind.
After a brief email exchange with Tim, you'd be supporting a good guy. He made a prog rock album to go along with it too! Unexpected, but still cool. Seriously, check it out.
As for World of Darkness, if you like the fiction in the sourcebooks then I'd recommend checking out a couple of the authors who now write their own fiction and/or create games. Chuck Wendig had a very unique style and I really dig what I have read of his so farit's easy to read and very entertaining; no one writes like Chuck. Reminds me I need to read Blue Blazes by him.
Greg Stolze is the other who has his own fiction, many of which his publishing model allows him to release as free ebooks with some of them for only a few dollars. Greg's games are pretty rad (to put it lightly) and one of his systems grew out of the work he did on the WoD linehe took the d10 pool and made it really sing. One Roll Engine is the system it became with Wild Talents being an actually good superhero game using it, and you should see the Progenitor sourcebook for it, OH MY! Alternate history that will blow you away!
One of his most well known games is Unknown Armies. Even if you don't care for the game (which is showing its age and I believe is getting a 2nd edition), get it for everything else that you'll love reading. The setting is beyond cool.
