New VCI user wants to upgrade to SE, help!

So now after a lot of believeing i've got my vci-100b ordered with an audio 4 DJ soundcard and i am ready to get into the world of digital DJing! (i'm a big newbie :[ ).

Anyway after reading alot on the site and the community I have read I have come to believe i want the SE version, so let me get a few things straight:

To upgrade I need to order the firmware kit from DJTT (available now I believe), true or not?
To fully enjoy the upgrade I should get the correct overlay too, true or not?

but the overlays are not available now and I could not find them in the list where you could mark your interest for the products, why?

I also believe the jog grips look sweet, when will they get back in stock?

Obviously for economic reasons it would be nice for me to be able to buy all these 3 things at the same time...

thanks in advance,
cheers big ears!
