MenaV2 has some good advice here. I'll try one. See if you can get a copy of Easton Archery's Tuning Guide.. This manual has a lot o good info about things such as basic setups right up through and including broadhead tuning, which is obviously what you need help with.

It's not necessary to have your vanes aligned with the vanes, but it is paramount to have the ferrules aligned with the arrow shaft (spin check). It is also necessary to have either helical fletching or at least staright offset. Left or right is not an issue with Thunderheads.

Don't let anybody tell you that broadheads don't fly to the same POI as field points. If the bow is tuned properly they will. Tuning any bow to shoot field points is fairly easy and often any imperfection in that tune will not show up until you put those nasty little blades up front.

Some might argue this, but it as been proven many times over that a bow/arrow combination can be grossly out of tune or mismatched and still shoot good groups, even at long yardages. That's because the bow, being a machine, does pretty much the same thing shot after shot. And if arrows are consistent from one to the next, they will shoot the same, too. Throw in some variables like inconsistent shooting form or grip, blades on the arrows catching air, and arrows will scatter.

Take that same setup, tune it to perfection, and it'll shoot hald dollar size groups at 40 yards---if you can. BINGO---for now I would forget all about broadheads. Learn how to shoot your bow. Learn how to have good repeatable form. Learn some basic tuning procedures and how to tweak a bow. Have fun most of the summer. Then maybe a month before hunting season get the broadheads out and fine tune your equipment for them. If you learn enough between now and then you might find it a whole lot easier to do.
