I'm not going to make definitive statements about the other things, but:
Dex DOES affect how fast you advance weapon skills, DRASTICALLY.
I worked my sadly-neglected 1HB skill up from 0 to 200 lately, as a level 45 warrior, and there ain't no doubt: low dex = forever. Werewolf form, +100 dex = zippity do dah!
I see the same thing on my level 11 Beastlord twink. He's been using 1-handers and recently inherited a nice hand-me-down 2HB staff. He has low dex though (70), and it's proving damn near impossible to get any 2HB skill-ups. (Already blew all my skill points helping other melee skills along.) I know you can get an advance without a hit, but still, advances seem to be (loosely) related to hits, somehow. And he just. never. hits. anything blue. It's tank and keep the pet alive, till the pet manages to kill the mob. REEEALLY sux. Maybe 2HB skill will move faster once it gets out of the single digits. I'm at 3, after 2 or 3 hours. Soon I'll break down and beg a shaman or chanter friend to swing by Shar Vahl...or, I'll toss the twink and start over. Vah Shir Beastlords appear to suck, compared to __________ (fill in the blank with any other race of your choice that can be a BL.)
