I will say this about the trim.  It's better in the first SP than it was in the original release. :)

Look on right side of the TQ, near the FO's trim wheel.  There is an alternative trim switches in the panel there, try them.  They move it much slower.

For me, I find that I am able to trim to any speed in climb/descent with the regular trim wheel assignment on my yoke and a little bit of correction input at the yoke itself.  But, to get in a level flight, I always have to set the AP to Alt Hold.  Once it has trimmed, I can typically take off the AP again and stay in my plan alt very easy flying hands on, so long as I don't touch the trim.  :o
