Right now, Collin, get the game up and running with GWX. Commander too, if you want, since it's stand-alone and you can put mods in and out of the game without Commander being affected.
There are SO many mods out there for so many things, give the game a go first with what you've got to get acclimated to it before you go nuts downloading and installing a bunch of other mods. With so much to choose from it's all too easy to get obsessed with mods to the point where you spend all your time downloading and tinkering and none playing! (I speak from experience here.)
GWX comes with quite a few optional mods already, if you click on the JSGME shortcut to open the mod enabler it comes with, you should see all of them listed there. Play around with those too, they're all designed for GWX so you should be good there (but check out the GWX manual for details on them first, or ask - some of them are only for use in certain situations, like patrolling the Black Sea or other specific areas of the world).
What are your system specs as far as OS, RAM, gfx card, etc.? FM Interiors is one of the "heavier" mods, as noted above.
