Currently there's no way to choose the order of albums - they are always sorted alphabetically. So you need to carefully choose names, or number your albums, to have them appear in a specific order.

You can update the order of photos within an album. It's a bit clunky, but the method is to go into the album, click the Edit All Photos (including hidden) button, then set the sequence numbers so that the photos are numbered in the order that you want them. The numbers you use aren't important - so you could use 10, 20, 23, 25, 30 or whatever, as long as the one you want first has the lowest number.
