Seems like a lot of comp shooters are shooting Hoyts', either the ultraelite or proelite. The Ultraelite can be had with down to a 24.5" draw with Xt2000 limbs, the proelite down to 26" draw with XT2000 limbs. Those would be two off the top bows on the market and would accomodate the shorter draw length. As far as arrows, stick with something like Gold Tip Ultralight Pro 22 series or Pro x-cutters. Take my opinion for what it's worth, I don't have much experience with women's bows. Look for longer axle to axle length with more brace height(7 1/2"-8 1/2") Good luck.
you might try archerytalk.com for more info. I don't know the price, but bare bow I would expect $750-850.
