Don't rush to failure. Have a plan, even if it takes time. Don't worry about practicing a ton right now if it means you'll buy arrows that don't fit your needs--then you'll be in a greater rush later when you eventually buy the right arrow.
General purpose, budget recommendation, even if you go to 70#: Black Eagle Renegades, 27" carbon to carbon in a 340 with a good fixed blade.
Detailed explanation if you care:
Put about as much money into your broadheads as your carbon. That matters more, ultimately. Many guys have issues because they can't keep their Walmart broadheads sharp. Magnus is a great budget option, but I also highly recommend Kayuga. You'll wait longer for shipping but you should sight in your bow before you shoot broadheads anyways.
If you shoot far or in windy conditions, go .203 diameter. If you won't shoot beyond 30 just shoot what you can afford. If you're asking for help, stay away from the .166 arrows because they require a lot of extra work and money to be worth your time.
Victory arrows are good, components suck. Black Eagle arrows are good, usually the components are good enough. Gold Tip has some pretty controversial components and good arrows. Easton has tough arrows and good components.
Everyone has this ridiculous idea of spine. It's a modern compound, you can tune the bow pretty well as long as the spine is close. Spine doesn't need to be exact, and they don't sell in .010 increments. It's not magic, you just need to visualize what the arrow is doing and adjust as needed. If you want a really big broadhead, then go for a 300 spine instead.
Keep your carbon to carbon length below your draw length. If you can't keep your fingers out of the way, you're better off paying for archery lessons.
Three Blazers, or four Pro Max vanes, are great budget options that are more than capable of controlling fixed blades and are quite durable as well. Super Sabers are good as well, but your shop may not have them. 1.5-2° offset is the sweet spot for most properly tuned setups. Do more offset if your form is inconsistent, do less if arrows come off the string spinning in the same direction as the offset.
If you want it in a hurry (I discourage heavily) then don't mix and match good carbon with other components. I'm assuming you want budget, because otherwise you'd probably just buy multiple and pick your favorite.
