LBR is the Chek-Mate person to talk to. I doubt if you go custom that it would be there by Christmas though. Maybe he has one in stock. Yes, you willneed an armguard.Some people go all out on it, some people go basic ( Ihave one from custom king that Imostly use, very inexpensive). You should probably get a tab and a glove. I'd offer you to borrow a few of mine, but you are a lefty. The glove might be OK,depending on your hand size (I use a large).PM me if you need to borrow a few, I have many. I'd recommend going with aluminum arrows at first. The size will depend onthe bow that you get, the draw length you settle in on, and your type of release. The chart at arrows by Kelly can get you close,but it may not be exact.

If you go custom, you may also need to knowif you plan on using split or three fingers under. I have only shot split in my life and don't want to change. But I also have nothing to compare it to. Others maybe more helpful on that.

Just wanted to show you a pic of my chek-mate Kings Pawn:
