Sideboxes and title text too big

[mampi]

Hi All

I am a newbie to Zen, have designed in HTML and CSS b4 tho. Have just gotten to grips with overrides and am tryin 2 design my 1st template based on template_default (not classic). You can see my design here:

I have 2 questions...

1) As you can see my sidebox widths are too big (the left and right column backgrounds are red so you can see how they overlap too much). I have tried to change Column Widths in Layout Settings using Admin, but this does not align the boxes correctly. I cannot find any CSS settings that help either.

2) Some text headings in my sideboxes seem to be bigger than others e.g. Search (left sidebox) and Who's Online (right sidebox), how can i make sure they are all the same size plz?

Any help would be much appreciated.. thank u.

To illustrate my point 1 further.. if u look at http://bestpixelpageever.com/sgp/ ,you can see then i have changed the left pixel width using Admin, however now the sideboxes on the left do not align correctly... plz HELP!!
