CSS Padding and alignment Issues

Guys my website is http://vigaversa.co.cc and it uses Deepfocus theme.

Its almost complete. 🙂

I have few problems though. In the posts section

1. The padding between two widgets in sidebar is too large. I didn’t find soemthing related in the css. Help me with it please.

2.See the “Confirm us that you are not a spammer” dialog below the submit comment button. I’ve just not been able to align it properly. Looks clumsy.

3.Fianlly, the main problem. I ran Yflow to test the functioning of the site. Got an C. The problem is, it says :-

There are 4 stylesheets found in the body of the document

How do I move these four to the top. I would be really grateful if someone can help me out. 🙂
