Compression, Rebound and Armpump

Looking for some input, here is the situation.

'98 YZ250 with stock suspension
190 lbs 5'10"
Motocross track riding at Novice level

Last week I added about 10 ml of oil to the forks which were at 135mm(manual spec with compression set at 5 clicks out). At this time my sag in rear was about 105mm and I was experiencing some harsh bottoming in the front. After adding the oil the bottoming was a little better and I noticed that arm pump had increased about 5 %.
This week I set the sag to 95mm (with 17mm of free sag) and arm pump has increased dramatically. The handling of the bike seems pretty good, corners are OK and it doesn't seem squirmish on straights, maybe I'm not being critical enough?
I was going to reduce the shock compression settings from standard by 2 clicks and increase the fork rebound by 1-2 clicks. Am I heading in the right direction with this?

Thanks in advance for the input.

I have increased my fork rebound 2 clicks faster and reduced my shock compression 2 clicks since I posted the question and the bike feels a lot better. I may increase the compression on the shock 1 click to tighten the rear end a bit. The bike doesn't seem to turn quite as tight but its not bad, I feel I'm getting closer to a correct setup.
And yes I do blame myself, I'm 37, somewhat overweight, somewhat out of shape and probably eat way too much cheese, pizza and beef jerky. Beer is good for conditioning isn't it. I am paying close attention to riding position and am trying to correct the things I'm doing wrong.
