Regardng your question about hosting, yes ofcourse there is always somthing better it depends on your individual site needs (present and future)...
As far as tgp scripts, well one i can think of right now would be Smart thumbs...
URL =
http://www.smart-scripts.com/?action...r1pg0d2n52ba04
It powers tgp backend so your free to create any design template for your surfers to see... You also have the option of using the free version for as long as you wish to see how things work out before you even consider upgradeing to the paid version
Yes there are others aswell. Look around and see which one suits you best. This is just off the top of my head. (Im still on coffee mode)
