Force Sensitive Archive

I searched the stickies and didn't find what I was looking for per se. Couple things that were close, but I would like some confirmation.

A little backstory first. I just started grinding without knowing what I was doing. I wasn't to worried about it at the time and it has come back to bite me in the arse now. As it should. Anyway...

Can I drop a tree and pick up another? Say I didn't want ranged speed anymore, can I take luck instead?

After I unlock, can I still do the quests for the reward? I may not get my sunrider's destiny this time around, but can I do it later type thing...

Also, is luck worth it? As it stands now, I can get the last two unlocks I'll need over the course of the next several phase shifts and I am debating just finishing off combat prowess, and picking up mdef and rdef and being done with it all. Any advice? Worth it to get luck or vehicular control or any of the others?

Thanks in advance for any help. It is greatly appreciated.

Qu3 - Yes get them now if you can then bank the fsxp but dont train untill it looks like you wont get the next unlock you want eg buggs then train to get padi which ever way works out .

BTW you can do all the unlocks if you want for the rewards just dont train the trees that you dont want/need.

Thanks for the reply.
