I know for sure that you get NO respec's on Elite mode, period.
Respec's are only available on normal mode and I thought they were free up until lvl 5. After that, you start paying.
Open beta has not kicked off yet, so if you don't currently have an account/beta key, you can't download yet. Wait for the open beta to start...shouldn't be too long from now.
If you do have an account/beta key, and haven't played since the Zone 3 release, you need to uninstall, download the new .msi build, and update. Your existing characters should all be there, but I would suggest having them sell all their items and mule the money on one character. Some items, such as gems, did not get upgraded to their new versions with the new build. Then, create new characters and transfer the funds via mail (must be the same game mode, i.e. Normal or Elite, HardCore, PVP) to give yourself a small "twink."
