Mtdm need moisture, so use a moisture retentive medium. If you use bark, use finer bark than you would use for a catt, and add a little sphag on top to keep humidity in the bark. You don't want to water so often you keep it *wet*, but it needs to be kept a little moist. Don't let it dry out completely.
Do NOT bury any of the pseudobulbs. PBs need to ride just on top of the medium, the way it is potted right now. If buried, they will rot, and the rot can spread, destroying the whole plant. (Ask me how I found this out).

How to repot? Get a pot one size larger, and put your plant in it at the same level it is now. DON"T bury the pbs, let them ride on top of the medium, just the way they are now.
I would not split it. A larger plant has more resources both for blooming and to withstand stress. You will get lots more flowers with a greater frequency from a larger plant.
New roots will form off the new pbs. So you may want to tuck a few threads of sphagnum moss around them to create humidity for the new roots to form. But repeat-- don't bury the old PBs
How to tell which are the new PBs-- are smaller and look new. New blooms will also come off the new PBs as they mature.
