New Multi User Script Issues

Hi,
I am just opening up a new blog hosting site and need some questions answered.

I am using the wordpress multiuser script.
Need to add what ever plug ins will help make it very user freindly (for everybody).

Need to add as many themes templates as I can for variety.

Need to add google type ads to this with option for members to add their own (And not display mine) by upgrading membership.

I would appreciate any help I can get. I am unemployed and need to start making money fast.

Thanks.
