This is a very nit picky comment but:
In the eCard categories, the headings all appear to be aligned using non breaking spaces. This leaves some of them appearing as you intended (over the first item in the list), and some of them hovering over the space between the first bullet point and the first item. As you are using your own graphics for the bullets anyway I would:
1 ) use tables instead to have them all aligned perfectly or
2 ) remove the nbsp's and have the headings at the very left.
The main body (between the two side bars) might look better separated from the side bars by using lines or colour. Also, the sidebars could be trimmed a little bit in width to give more space to the main section. By the way, the right sidebar shows up funny on my screen (15.4" laptop, running FireFox on WinXP) The green and orange bars and dotted lines run over into the main background of the page.
I would also look into using graphics for the menu at the top (next to the logo)...your logo is very flashy (and nice!), and the links look incredibly dull next to it.
Just a bit of constructive criticism, other than that the site looks great, although I agree that the animation should stop after 5 seconds. Good luck with it, it's a great domain and the site looks to have great potential!
