Opinions on the obvious design changes

After shopping around this past week for domain names, other blogging platform software, service providers etcetc I came to my senses. 1) I have little money to spend in the first place 2) I know little about coding or anything IT related, apart from a little I've had to pick up from necessity 3) I remembered there are good three column blogger templates out there, I just had to go look for them. So, I went with door number three and it was less of a hassle to swap over than I thought. Of course, as you can see, there are housekeeping issues I need to sort out, like re-doing all my links, but I can do that on the weekend. The banner up the top has grid issues, and I have been thinking is too small anyway (So I may have to hit up my friend who did the first one to, maybe, see if its possible to re-do.....? She knows who she is!). I'm not sure I like the font that's defaulted to be used. I was sick of a plain white blackground, so I went with the silver? Nice? What else do you all reckon? What needs tinkering with?
