The jump 2 light speed quests you can get in to when ever you are ready, just pick a faction and a starting location (tat, naboo or corro) you should find a wp to the starter trainer for each faction on your map. Then your off on your way to grinding out your pilot prof.
Rage of the wookies, well thats a lil more complicated, there are many many new quests on there, but like JTL once you have your ship off you go (you can only get to wookie world by flying, hyper space to the neutral terrotories and fly to the station) pick the quest you want to do (you will find lots of information on the main quests and how to get started on them in other posts on here) although you may find you require a higher combat level than you are now, and you will have to work your way up your pilot skills to at least teir 3+ to do much of the space content involved with ROTW or you could do the old get harder friends to help out trick.
Hope this helps, for more information just post your questions
