Let me preface this by saying that I do not have a Static and the highest end content I usually do is EX Primals in PF PuG groups. That being said, until a Savage raider would like to step in and offer something more constructive, my basic advice is to educate yourself and put effort into being the best you can right now. I personally recommend the Balance as a great resource.

Pick which class you would like to main and focus on gearing it up as best you can in the short term- buy the new tier of crafted gear or burn your tomes for the best vendor gear you can get at the moment. Replace your lowest ilvl items first. Once you have decent gear that you don't feel you'll be replacing in the immediate future, meld it (I would save overmelding for when you get BiS or once you find a static, if they require that).

Do research on your chosen class and make sure you are optimizing your rotation. Watch boss fight videos to learn the strats before you ever set foot in them. Make yourself a player that other people will want to have on their team.

I know it's not terribly specific, but I hope it helps. Good luck out there!
