Self only movement skills:
Man-at-arms - Battering Ram
Man-at-arms - Phoenix Dive
Expert Marksman - Tactical Retreat
Scoundrel - Cloak and Dagger
Movement skills (cannot target self):
Aerotheurge - Teleport (includes a damage component)
Aerotheurge - Featherfall
Teleport can be used to move other characters or items such as chests and barrels but should not be used on friendly npcs or companions as there's a damage component. Your two PC characters can be teleported without other consequences than taking the fall damage.

Vendor refresh:
Vendor items will refresh the first time you have gained a new level and choose barter with a vendor.
Save-scumming vendors is a tactic that means you save before choosing barter and if the vendor doesn't sell what you want you reload and try again.
I've also built a mod that makes vendor items always refresh, but it isn't properly tested and will increase the time it takes to open the bartering screen. I would not recommend using it on a first playthrough. (can be found in the Mods-subforum.)
