Do you actually have to SHIP the reptiles to your new home?
If it's just travelling by car, I use shoeboxes for my chameleon and deli cups for my other babies.
If you're actually shipping I could invest some time into finding a good carrier, as I'm sure you care about your animals. Look up Tony's (Boas_N_Pythons) post on shipping snakes, it's the most complete guide I've seen, and it can be applied to lizards. I'll look it up and edit it in in a second. People ship those kinds of animals everyday, it should be fine.

For future reference, this post can be found in the HOW TO section at the bottom of the forums list.
As to your question about the geckos I would ship them seperately, but I don't see anything catastrophic happening if you don't. Just IMO.
I know how you're feeling, moving houses can be crappy. I moved from a tiny little town where I knew everyone, to Ottawa which is huge and I'm pretty sure has a funny smell that I'm used to now :flick: Starting out in a new place has some really cool benefits though. In 2-5 years my parents are kicking me out and moving to Arizona, and while I'm expected to have moved out by that time and don't get to go, I can't wait to visit and go herping down there
Good luck
