One last question, the sidestick, is it programmed to give a stick force feel, (I think it is?), and will it show sloppiness at low speed, tightening up at high speed as such?
No - it's passive spring feel. Breakout from centre position and you know you're doing it, it's a chunky piece of kit! Very well balanced though - check out the summary

Why the need to autotrim the stab with sidestick input?
Easier for the PF, bearing in mind there's no force-feedback. The autotrim system works just fine, though it means that the Airbus FBW series is a little different from a conventional setup there. Interestingly in the A320 sim we found that the trim would stop at a certain point, and had to wind it back manually to simulate AF447's condition - this is apparently different from the A330 which will autotrim all the way if the pilot appears to be demanding it.
