Yes, shoot the heck out of does. Stop shooting bucks until you achieve a healthy mature buck population and then be very selective and conservative. But keep shooting does.
On my last lease (well managed, MLD 3) we literally shot every doe we saw in order to achieve our numbers as set forth by the biologist. Sometimes it was quite difficult to kill the does that we were required to shoot (typically well over 100 does for 5500 acres low fence). Even still we maintained a 1.5:1 doe:buck ratio.
Benefits are that you'll have mature bucks and fewer does, meaning that bucks had to compete to get does and they had to search for the does that were available. It certainly improves your chances at seeing mature bucks.
I'd begin with a call to TPWD and see about getting a survey and recommendations.
