Problem with space on the top from sidebar and wrong coding

Hi,
I’m making my own theme, but I don’t know why my sidebar is little lower than the rest.
I have a problem with character codding too. My language is Polish. Could you help me?

Here is my template (you must copy it to templates directory): http://skycast.pl/download/SkyCast.rar

And here is screenshot: http://skycast.pl/download/1.jpg

Sorry about my English 😉
