you can cut a big chunk out of the main quest, heres how;

when you get out of vault 101 proceed to megaton but dont look for your dad, go to craterside supply and speak to moira brown, she will ask you to do a quest for her ( Wasteland Survival Guide) do all of the chapters untell you get to 3 she will tell you to go to rivet city, from rivet city, speak to Doctor li, and then the GNR bit out of the main quest will be cut out

Hope you find this useful :)
