[Vwdiesel] changing the timing belt

Does this sound right, or at least normal? after replacing the water
pump and the intermediate shaft seal I proceeded to replace the timing belt.
I got the camshaft, crankshaft and IP pulleys all in their respective
TDC positions. I didn't want to take the cam pulley loose, so I ended
up slipping the belt up onto the IP pulley last. Though the tensioner
was set for minimum tension, it was difficult to do but I don't think I
damaged the belt any. Once I adjusted the tensioner though things
shifted just a bit.
Now with the crank at TDC the slot at the back of the camshaft isn't
quite parallel to the head - it looks to be a hair advanced, maybe 2 or
3 degrees. Also, the IP is a hair advanced - more like half a tooth's
worth, as it seemed I could either have put the belt on where it was
half a tooth retarded or half a tooth advanced, no in between. How
close do I need to have these set for the engine to be able to operate
reliably, or should I say optimally? Should I take the cam-sprocket
lose and realign? I haven't run it any yet, other than to turn it over
by hand to see if things shift any more (it didn't).
One other question: The pully on the intermediate shaft is not a tight
fit on the shaft, it moves maybe a degree either way before the key
stops it. I tightened the bolt down to about 70 ft-lbs. Also, is it
normal to be able to slip this pulley around against the T-belt after
the tension is set on the T-belt?
As always, thanks for any input.
