Several questions

Hi there once again.
Here’s a set qf question which shouldn’t take too much time for a pro to answer:

1.) I’d like to have that “This entry was posted”-block in the comments-section down, under the text-entry-area. What must i change and where?

2.) I’ve thrown away the text-based sitename and -description in the header, because i have a own graphic in there. Now, where do i (and how) set this image in a way, that if i click on it i come back to the homepgae?

3.) I would like to have the date of an article ABOVE the headline. At the moment it’s BELOW the headline. Where do i change this?

4.) My footer should always be at the BOTTOM of the browser window – because in “shorter” pages it “floats” around … looks crazy.

Okay. That’s it so far …
