Use whatever you are most comfortable with and build your way up. There are so many different options for accessories that some really help and some not so much.
I think speed is over rated. Personally I think a bow that sits perfectly in ones hand is very important. The "kickstand" side stabilizers are huge when it comes fine tuning the balance off setting your sight. If you can't open your hand and have your sight level stay in place, you are going to torque your bow and accuracy will suffer. Another big thing for me was shooting a bare shaft to see which way it rotates before fletching. One last comment I will make is to draw your bow with your eyes closed. When at full draw, anchor everything so that it feels comfortable. When you open your eyes if everything isn't perfectly lined up with your peep sight and the bow is level, make adjustments.
It's hard to find good archery shops that will take the time to do these little things to get you set up. Most know their stuff but when it's busy, they can't take the time it takes.
