Everyone will want your sw account posted to give you proper advise. However, I would suggest finishing one team before moving on to JKR. All your resources are better spent on farming your BHs for Chewie not spread out. You can spend excess currency on JKR characters after you have done your refreshes etc but not wise to spread it out or you will have a couple long farms on your hands with little progress.
Just my 2c based on what you wrote, I am by no means an end game player so take my advice with a grain or two of salt. Good luck.
