<-- greeting and intro missing -->

I first heard of [company] from [friend], a former employee of
yours, and per [their] suggestion I am now applying for a job with you. I sent my
curriculum vitae along with this document for your evaluation.

I expect you to find my abilities to your liking. If desired, [friend] can attest
to some of those abilities, namely my ability to learn fast, and my expertise
with the C++ programming language and the English language.

I am currently living in Portugal, but I am willing to relocate to [city] if
this application is accepted. While I do not speak [language], I believe I can
rectify that in a short amount of time.

I look forward to hearing from you.

Sincerely,

Martinho Fernandes

1. Is this too long?
2. I need a greeting, a short introduction, and I'm sure "Sincerely," is not the right goodbye thingy.
3. Should I mention in my CV that I blog?
4. Should I mention in my CV my contributions on SO?
