Activate Buddypress on Multisite Sites/Blogs

When I create a new site on my Multisite enabled, BP activated network, how do I do the following:

1) Ensure that BP is activated on the newly created site
2) Make sure that the BP menus /blogs /forums etc are active on the newly created site
3) Use Default Blog Template to make sure that the newly created site has the initial look and feel that I want (a variation on the main site).

Should I upload the BP plugins to the mu-plugin directory?
