IELTS & NCLEX advice

I just took my IELTS last Aug. and I don't have any problem in my written exams L:9 R: 6.5 W: 6 but my speaking is 6.5. I'm planning to go for the rechecking process... should I take the risk? Secondly, I already have my NCSBN report that I passed my NCLEX-RN, does it guarantee that my files won't be destroyed anymore in CA even I don't provide them a SSN? Coz, it will expire next month already(October 2011). thank you for your help. Godbless
