Only one advice, patch it and, depending on the version that you have, install a children patch. The developers removed children from the game on some versions because, well, you can kill them, but they did not remove certain quest chains and other interactions that involve children NPC's, so those are just dead ends.
Other than that, just enjoy and explore it, FO2 strikes a perfect balance between a scripted story and a player-defined outcome on pretty much everything. It's gonna be whatever game you make out of it. I still remember the massive, Godfather-like showdown that I orchestrated in New Reno by playing everyone against everyone else as one of my gaming highlights, but I could have just walked in and done jobs for only one family and then gone somewhere else, the game never restricts you and there is never only one solution to a problem. You can read up a bit on most walkthroughs that include some tips on character setup and which stats are more useful than others etc, but read no further than that.
I played this game on release and without internet or guides and to this day it is my second favorite game of all time.
