It's not hard once you get used to the layout, like any other site.

Click on the Second Life logo near the upper left corner of this page.

Click on "log in" on the next page.

Sign in with your account name and password on the next next page

The page after that is your dashboard. Your transaction history is filed under "Account."

As for deciding which categories your questions should go under, just make your best guess.
