The truth is - you don't, at least not until you get there. And what might be good for you, won't necessarily be for someone else. There are no books which have a formal ranking system or evaluations; and besides, once a book gets published, the data is already outdated.
Unfortunately, some residents will not tell you the truth about their program - leading you to believe everything is hunky-dory and OTOH, some will only tell you bad things (ie, many review sites only contain negative information), leading you to believe that a particular program is a hell-hole.
First you must decide what is important to you - this usually falls along the lines of geography, a more research oriented vs community practice type of residency and family issues (ie, does the community provide job opportunities for your spouse, is there a lively singles scene if that's what you want, etc.).
Secondly, you should talk to residents at your current program as well as faculty and get their feel for what programs you might be interested in, and what their take is on the programs. Be aware that many faculty may be out of date as to what the program is really like (especially if they trained there 20 years ago), and that residents won't really know unless they rotated there, went to medical school there or have a close friend there.
Thirdly, if you are thinking about a competitive fellowship after general surgery training, choosing a program which has exposure to that specialty (but not necessarily a fellowship in that field) is a bonus - it gets you exposure to the field and its practitioners.
When you interview at a program, if there is a social event the night before, try and go - see how many residents attend, see how they interact with each other. This requires reading between the lines and observing human behavior, not necessarily believing what you hear.
Finally, if you are the type that finds academic ranks important, while there are no formal rankings for surgical residencies, there are several threads herewith which offer conventional wisdom on which ones are respected. Keep in mind that these tend to weigh heavily towards university, academic programs and not community or private practice ones which can be excellent and may be the best choice for you.
In Texas, the programs often mentioned as the "heavy hitters" are obviously Parkland (especially for Trauma), UTSW (especially for Plastics), Baylor in Houston, and of course, MD Anderson for Surg Onc. Scott and White has a good rep as well, and U of Houston has been reamed rather thoroughly here. Check the forums for some info on specific programs. Here's a link to a recent thread...
