Clothing content for Ryan and Alyson are now found under props as it should have been defined from the very beginning.  See illustration.

The blue android, Andy, is now the default mannequin for both Poser 8 and PP2010.  You can always change it out for Andrea or any other figure you desire. 

I recommend that you take a look at the manual, it does contain basic operations.  The layout has changed and new features have been added, otherwise most tasks remain the same as other versions.

BTW, do install the latest service release, it corrects some problems discovered in the original release.
