Honestly, with the reaction to part-time programs, I'd go to a lower-ranked school and try to transfer up. Also, you ideally need your summers to start looking for firm gigs. So if you're working full-time and doing PT the "right" way, you are also potentially getting off track for the law school job chase. You will find that in law school you are perpetually applying to jobs/clerkships. But if you do PT without the FT job, you look like a slacker/backdoor to employers.
Bingo. If there's anyway to do FT do it.
