I've been in your shoes. Its rough, fortunately for me, I was able to get hooked up with a great bunch pretty early.
I agree with Elk hunter. Your arrows are too stiff. That is a huge part of your frustrations. I would try putting at least 100 grains more up front or move to a 500 spined (not spline) shaft.
As far as arrows go, I bet an email or private message into Big Jim (sponsor here) and he would be able to get you arrows close to what you need. He has blems in stock which will save on the wallet.
Out of my 45 lb bows, I shoot 500 spined shafts. they are cut to 29 3/4 with 225 grains up front. If you cut your arrows shorter, it stiffens them and you will need more weight up front to bring the spine back down.
There is a big difference between compounds and Trad because compounds are usually center shot and allow for more flexibility in spines plus you shoot with a mechanical release which also allows for more flexibility.
Get proper arrow flight then work on Form. With stiff arrows, your arrow bounce off the shelf and fly all over.
Good luck, dont give up and ask questions, thats partly why we are here.
