1: Respecs are coming soon. The only thing we know for certain is that they'll be in place when they add the last 5 levels of content to the game.
2: Yes. B'Tran can only be done once every 24 hours, based on when you took the mission.
3: Based on Criticals and Accuracy the anti-protons seem to be better beam weapons.
4: No. The Devs have only said they're working on it.
5: I haven't purchased any of the purple items and did quite well in all the Borg missions.
I am going to attempt the borg missions without the purple items too. If it doesn't work out I can go ahead and do the daily exploration missions to get them You didn't mention anything about the tricobalt torps. I read antoher post that the quantum torps were considered the best in pvp. Now those I have, and so far they have cut enemy ships down quickly. I would like to test the tricobalt though. Has anyone done any thorough testing between the 2 on various ships. I would like to know the results.
