Wordpress Tweaks2

Hello, I would like some tweaks completed to a website. 1. The Buddypress menu changed and restyled. The "Home Admin Members Groups, etc" menu is too small, not properly spaced and just plain ugly. Enlarge it, style it - text or images is fine so long as it stands out and blends with the site. It's an important menu. 2. - remove "visit blog": Example link: [login to view URL] 3. I want more posts than three to show up in the groups, maybe 10 posts. Example url: [login to view URL] 4. Remove the group avatars Example url: [login to view URL] Thanks,
