If you include Joe Perry's AAFC (folded after 1949, 9ers Join NFL in 50) yards (which the NFL doesn't in the stat book) he had 9723 and 2021 receiving. Gore has 9134 and 2687. So 11821 for Gore, Perry 11744... Gore has more all purpose yards but is still technically 589 away from tying Perry although since they don't count AAFC's yards for the NFL Perry had like 7344 so Gore passed him long ago for that. So assuming no injuries Gore should pass him for real and truly cement himself as the 49ers all time leading rusher.

I think these guys would be in my top 9. It depends if you rank them based on career or per season.
Frank Gore, Roger Craig, Joe Perry, Hugh McElhenny, Ken Willard, JD Smith, Garrison Hearst, Ricky Watters and Charlie Garner
Hearst, Watters and Garner had amazing years but there stay with us was way too short. And to the question is he a top 10 9er I say yes he should be somewhere near the bottom of the top 10.
