it's all so new...

I've wanted to blog for a few months now, and I need to learn a lot of things! I need a lot of help! I downloaded this free design from a website, but don't know how to get my twitter to link, or for that fact-anything else!
I am currently at work, using my 12 hours of patient care, to blog!
I would appreciate any and all help/suggestions!
love,
lauren
