I've never worked with dymonwood, but it sounds like some issues I have had with bloodwood & ebony. I have to exert some pressure with the barrel trimmer to get it to cut and when it does cut it feels like I don't have a lot of control with it. I've managed not to damage anything so far. You can try one of the sanding jigs, but I still prefer the barrel trimmer.
Drilling the acrylic is similar to drilling any of the denser woods. It helps to have some sort of dust collection to catch the ribbons of acrylic that come out. Don't try to drill the whole segment at once. Drill some and then back out. Some turners will cut the blanks a hair longer than necessary and not drill all the way through the blank, then go back to the chop saw or whatever you use and cut the blanks and cut them to size. This prevents blowout. I've only had one blank do that on me, frustrating, but it does happen.
As far as the Euro's go, look back to the "Looking to learn how to turn "Designer" model pens" topic from last month. There was a lot of good adivice given for that topic: http://tinyurl.com/dmv89. No sense going over it again. [
