Here is a different outlook that may provide you with a few more options.
The first thing I would do is find out what deferment options Rutgers and Houston offer. What I have seen tells me that they would want some kind of commitment from you (that you won't go to another school) but I don't know how serious schools are about this... so check. I don't think a retake will get you you to notable schools in CAL or T14 schools, but I do think that it will give you more options for regional schools in the T30 (and of course there is an outside shot at T14). Many of those T30 schools seem to be putting a premium on high-end LSAT scores, and with applications down you will probably be in an even better position next year without much of a jump.
It seems like this Houston offer is just a reason not to go to Rutgers. My advise would be to talk to schools about deferment, spend some time studying for October/December LSAT, get your relationship in order, research and visit some T30 schools who are friendly to your numbers. Just don't move across the country because you don't like Rutgers that much.
