Under the federal TA program as an "active" drilling member of the Guard/Reserve you can get up to $4500 a year for any school, by submitting a DA 2171 through your unit.
If paying for school is more important than entering AD, you may want to consider submitting a DA 4187 to cancel your ED delay and enter the National Guard. Most states offer pretty good post-grad education benefits; out of state fee waivers, reduced tuition and tuition assitance beyond the federal TA program.
Depending on state you could get most if not all your tuition paid for.http://www.gibill.va.gov/education/StateNGAid.htm
But then you open yourself up to having your OBC, drills and above all deployments interfering with your law school plans.
