assuming that you are guiding at a bit below 1 arcsec/pix, that would be a pretty standard result - most seem to be getting around 8 arcsec p-p with a few getting better.
the drift looks normal to me, maybe a bit of PA error in there.
interesting comment on the axis drag - mine is similar and I thought of backing off the bearings, but didn't yet. Be interested in how you went about it - looks fairly straightforward, but then so do a lot of things.
FWIW, I have found that short guide exposures are useful - I use a fast guidescope and normally guide at 0.5s. The EQ8s have low PE, but what little there is changes pretty fast, so I get best results with fast updates.
