Does anyone know what resolution is the 35mm film scanned at for the digital re-mastering. And what resolution do they increase it to before they record it onto 15/70mm film?

IMAX uses the same gauge film(70mm) to shoot and project.

A 35mm film at your local theatre might go through a 2K, or 4K DI.

IMAX DMR projects have gone thru a variety of post paths. Most just use the D.I. data files (usually 2K) for the 35mm release, de-noise, de-grain, and re-sharpen them for blow-up to IMAX, but for "Batman Begins", which didn't go thru a D.I., they used a 35mm IP and scanned it at 4K for most of the movie, and 6K for a few wide shots, but remember that all the visual efx were done at 2K.

Do they increase the resolution during the de-noise, de-grain, and re-sharpen phase?

Probably they uprez it to whatever their Celco 65mm film recorders output at, but it doesn't really matter -- what matters is the resolution that the work was done originally at. Uprezzing a 2K file to 6K isn't going to help much.
