Change from 5.0.2 on XP to 5.0.2 on Vista

I think that the suggested way to move from running PSE 5.0.2 on an XP computer
to running PSE 5.0.2 on a Vista computer is:

On the XP computer, backup PSE (in my case to DVD's). My catalog is in the
default All Users folder and my pictures are in many subfolders in the My
Pictures folder under <myusername>.

Then, on the Vista computer, switch to my Administrator account and install PSE
5 from the CD, and then download and install the 5.0.2 patch.

Last, switch to my User account, open PSE and restore from the DVD's.

Am I on the right track?

Will the catalog wind up in C:\Program Data\Adobe\Photoshop Elements\Catalogs?

Will the pictures wind up in C:\Users\<myusername>\Pictures?

Does it matter that <myusername> is different on the XP and the Vista
computers?

I'm happy with PSE 5.0.2, but would this go better if I installed PSE 6 on the
Vista computer?

Thank you for your help with this.
