Plumbing – do about a toilet drain pipe that is too high above the floor

My toilet drain pipe protrudes about 1/3" above the floor, and makes the toilet wobbly. What can I do to fix this?

Assuming the flange is sound (it looks pretty worn and rusted), you might try to create a ceramic tile platform that would lift the bowl to be flush on both the flange and the floor. You are right that a lifted flange is a problem because the wobbling will eventually break the wax seal and allow leakage and smells, to say nothing of making the user uncomfortable.
It looks like you have some type of vinyl flooring under the bowl now. if that is the case, you could work out a tile layout, at least a bit wider than the footprint of the bowl, then trim the vinyl just ouside of the new tile boundary. Remove the vinyl and affix the ceramic tile to the subfloor. You may want to use a tile membrane base over the subfloor and under the tile for better adhesion and water resistance.
Obviously, you need to find a tile that will be just high enough with the vinyl removed and allowing for the membrane (if you use it) and a bit of tile adhesive. After the tile is set and dried, you can seal the the new tile platform to the rest of the vinyl flooring with a good quality caulk or silicone sealant.
If the flange is not solid (and the bowl is bolted to the flange), it needs to be replaced, usually a job needing professional help.
I ended up cutting off the top of the flange with a PVC pipe cable saw. I then used a mini hacksaw to cut some segments into the fitting and wedged the pieces out. After removing 2 small parts of the ring, the rest just wedged right out without much effort. I cut down the pipe to be flush with the floor using a pull saw. I put a level down and found the concrete was not level around the pipe. I used a rub brick and the mini hacksaw, which I could angle to cut the inside of the pipe, to get the pipe and surrounding concrete truly level with the rest of the floor. This took a while.
When I finally got it level, I put in a Twist N Set Closet Flange. I drilled 4 pilot holes and put in concrete screws. The toilet is now level and not going anywhere. Now I just have to fix my guest bathroom which has the exact same problem. At least I got a good deal on the house.
You must have a vent. The toilet will not flush properly without one, and there will rarely be enough water left in the bowl. You need a 2" vent to take off from the branch line within 6 feet of the toilet. It can run up any convenient wall until it is above the toilet's flood level. Then it can run near horizontally (1/4" per foot) anywhere to tie into an equal or larger vent.
There's any number of ways to properly vent a toilet, and several common ways that are technically wrong, and even more that are just plain wrong. It's impossible to suggest a good method without a lot more information.
