i have 2 months old site i've prepared for Google with one keyword pharse. it's PR4 right now and keyword is in all anchor texts that links back to me. keyword is not very competitive, i've chosen sth easy for the begining.
the problem is that i'm not in serps for first 1000 of results

.
i understand that my site can be not tweaked professionally and not be in first hundred, but not in first thousand?

so my question is: when do i know it's sth wrong? should i change my keyword density etc. or maybe should i wait because it's too new to be in serps?
and the second question: are seo boards' advices worth sth? i'm asking because it's everywhere written that the same colour for text and backround is a spam and one should be banned for these practics and #1 result for my keyword is mainly same colour of text and background.
help plz
