Mods/upgrades - FN herstial

[Cheeserush]

Looking to draw from people's experience of teching and upgrading, it isn't something I have shown much interest in however I am starting to be a little curious! So from what I know the springers are the easiest to start upgrading. So I am looking at my FN herstial to upgrade, and I believe the parts are vsr compatable however I'd like to know what certain bits of kit do to help me upgrade how I would like. So I'd like to know what things are for such as spring = more fps etc etc and any impacts that will have on the gun. All information would be useful as I say! Also just on the back of this does anyone know any websites who do a good upgrade service?

Thanks!
