Welcome to the forums and the world of subies!
If you have specific questions, go ahead and ask, otherwise have a stroll around, there's threads for quite a bit of information; I've lerned a lot from being here..
Other recommended reading is some of unabomber's manifesto (either search it, or wait for the next reply to have the link ) - that'll tell you a lot about different mods and what they do. Otherwise, there are some goog guides for buying cars, doing first mods, etc. on here.
Btw, you can set it up so the forums email you on replies.
