Several questions about DSP-122 and DS-230

[cardray]

DSP-122
* "6. Education", I specified "Other: College Diploma" If my mom studied in the school similar to college and if she have a diploma is this correct to put "College Diploma" into that field?
* 7c (7. Work Experience, "c. Names and addresses of your Employers ...") - as I understand if I am not going to qualify under Work Experience, here's no sence in writing any experience in the "c." fields? Or I can write there anyway?

DS-230
* What I should write in 10th and 11th question (U.S. address for mailing GC, and for showing consul where I am going to live) if I am going to say this address at the interview? (Because I am afraid that probably finding address will take a little bit more than I am expect and I want to send this forms faster before knowing U.S. address)
* The most inconvenient fields in both DS-230 and DSP-122 is fields about education institutions, employers, present occupation and other stuff which I can fill by many way, by any phrases because e.g. I can translate educational institutions etc into English in many ways, and I am confused about all this stuff
* Signature of applicant and date of signing at the page 2 of form DS-230. Should my mom sign it at any date? Or here's some specifics about this field?
* "Other Names Used or Aliases (If married woman, give maiden name)" - what if my mom was married, then divorced? Should she list her husband's surname when she was married (marriage lasted 15 years, and all this 15 years my mom used my husband's surname, doesn't this should mean that she should specify it here?)

Another one question. There's a section "Languages spoken or read", and when I asked my mom to write all her spoken or read languages, she gave me a lots of languages: Tatar; Bashkir; Turkic; German; Tadjik; Kazakh; Kirgiz (should I mention here her native language: Russian?)

The question is - the level of her knowledge of this languages. In most foreign languages listed above - she can't talk properly, but can understand even then she probably have very low level of understanding. And at the one hand it probably would be useful to know so much languages, at the other hand - consul can become suspicious about competence of my mom, and he can think that she lies (what if my mom won't be able to prove that she can properly understand this languages?)
