What is a quick-release?
A quick-release clamp enables you to quickly raise or lower the seat post. One QR type is a bolt and 'nut' with a handle. The preferred type has a camming lever inside the nut. The obvious advantage to QRs: no tools required.

I was just wondering what size the seatposts are in diameter.
Most unicycle that have been manfactured since 1990 have 22.2-mm seat posts. This includes: Coker, CycleDesign, CyclePro, Fleet, Jugglebug, Miyata, Onza, Quentin, Savage, Semcycle, Schwinn, Torker, United, Yuni and Zephyr. The rest, in millimeters:
DM Ringmaster, ATU: 25.0
DM Vortex: 27.2 or 26.8
Hunter: 26.8 (with 22.2-mm adapter)
Kris Holm Pro Series: 28.8 (with 22.2 or 27.2 adapter)
Kris Holm (Taiwan version): 27.2
Pashley: 25.0
Wilder: 25.4

The seat swivels when clamped, is there a way to prevent this?
If you're referring to the Savage-style seat, yes. Use a long wrench (which gives you more torque) to tighten the nuts on both sides of the seat clamp (not the seat post clamp). There should be only about 1/4-inch clearance between the clamp sides when they're tightened sufficiently.

If your have a quick-release lever has a camming mechanism inside (standard on Savage, Torker and some United models), tighten the lever by spinning it clockwise, then flip the lever 180 degrees (like turning off a main power switch) to 'lock' it down. The camming mechanism tightens it a bit more.

How do I know which seat post length is the right one for me?
A good rule of thumb:
If under 60 inches in height, order a 200-mm seat post.
If between 60 and 67 inches, order a 300-mm seat post.
If 68 inches or above, order a 400-mm seat post.
Note: If the size seatpost you select is too long, it can be shortened with a standard pipe cutter.

Will the Pyramid Suspension Seat Post fit on the Miyata saddle?
No. Pyramid suspension posts start at 25.4-mm (1-inch). Miyata seat posts are 22.2-mm (7/8-inch).
