I've had a 10/22 since I was 16. Great rifle. Honestly, leave it alone and spend your money on finding ammo that shoots well and feeds well with it. The only mods I made was a quick mag release and a good (Leupold) scope. I can hit a dime 3 times in a row at 50 yds. with the right ammo.
I had a Marlin in .35 Rem too and they pack a serious wallop at close range, more so at 100-150 yards than a 30-30. Great rifle!
