In regards to your load screen time, I have an SSD and it takes less time than WoW Load screens (also on my SSD). Maybe its your setup? I have never seen this 'laggy' complaint. I agree the UI is crap, but they are working on it and addons are coming (I expect to see macros by May's 1.3 and addons by July's 1.4). Professions are professions and there is not a lot of ways to do them differently. The fact you CAN send your crew out to gather for you you while you do other things is pretty damn awesome in my opinion.
As far as the voice acting, the only complaint I have is they skimped on the alien languages (cant really blame them, though). Other than that, I like the voices (IA male is the most awesome voice/class match up ever). As far as the story being dull, so far I found the class stories to be sweeping and epic. I haven't played them all yet, but I will eventually. And I HAVE read most of the books. Heck, I probably read more in a week than you do in a month... (I know that last line is trolling but so is the posters implied insult about reading)
