Limestone sealing

[On one]

Is it feasible to grout crema g Limestone prior to sealing? Not something I would normally do but.....

Tonight I have just finished tiling a small downstairs shower room walls and floor with 600x400 tiles and will go back tomorrow to get everything cleaned down.
Now normally I would wait a few days for the stone to dry before sealing,grouting and sealing again,but
would grouting before sealing be advisable with this type of tile?

Your normal professional approach sounds good, as you state above. I would stick with that. If your cleaning down, you will also have extra moisture to release. Let her dry,

Cleaned the tiles down and left them to dry for a few days prior to grouting. A bit concerned about how wet the cut tiles look like compared to an uncut tile(water from the wet cutter)
Can a water based sealer be used on slightly damp stone moreover than a solvent based sealer?

If you have colour difference, do not seal . This could trap moisture and water mark ( stay dark) . Let it all dry, this is annoying for you with the timings to finish, but will be worse if you then need to remove tiles. Water based will not bite you as much as solvent but would still recomend that the tiles are fully dry for both.
