i found reading this treatment manual really very helpful. i learned about a variety of treatment for BPD that has been shown to be effective, and the author also explains things in a way so that i could see what therapy was supposed to be about and even more importantly how therapy was supposed to help me.
it is expensive to buy but i really think it is the best book ever written on borderline personality disorder. it is well worth getting it from the library and photocopying it IMHO:
