I've only ever flown one PA28-140. One thing which might catch you is that the ASI on the one I flew was in MPH. Lots of people here are quoting you speeds in kts. Make sure you use the right numbers!
As for the trimmer, a hint from my old instructor was to always try to leave it positioned side-to-side, pointing towards the left. That way, when you start winding it, it moves in the correct sense. (If you leave it pointing to the right, it will move in the oposite sense, and if you leave it pointing fore-aft, all bets are off!)
