Trying the stock 1.3 game first is a good idea. See what bugs you (no pun intended

) and then check for mods for that item.
That said, here's what I'm using at the moment:
Green button mod
Battle stations/silent running on all menus mod
Living Breathing Ocean mod


Natural Sinking Mod
Real Diesel sounds mod
And probably one or two others that I'm forgetting.
Good luck and good hunting! Enjoy that new rig!
