razzle0146 on "Raindrops Theme"

I am currently using the RainDrops Theme and I want to
1. Remove the Page Titles from the pages.
2. Center the header menu.
3. Increase the font of the header menu.
4. Increase the spacing in the header menu so it spaces itself from the left to the right to both edges.

Any help would be appreciated. I have searched and searched for the answer but cannot find it.
