PermissionsBukkit is a primitive, bare-basic permissions plugin. As such, many features may be absent from it. This is one of them. You can try using superpermsbridge, but you may have very inconsistent results. You're better off just switching to another permissions plugin. It'll take some time, but you'll save a lot of time in the long run.
My permissions plugin of choice is PermissionsEx, or PEX. It works well, and it has a very nice command system for simple edits to permissions files that don't require pulling out the whole .yml file. It also has a compatibility layer for Permissions 2/3.
Another popular permissions system is bPermissions. It, too has a compatibility bridge for the older systems. bPermissions focuses on being lightweight and fast, but it loses some of the features of PEX in exchange.
On the other hand, any plugin that doesn't support Bukkit superperms is probably pretty outdated, anyway. The latest version of mcMMO can handle superperms (1.3.09 as of this writing).
There is a simple way to combine your Multiplayer world for Single-player use.
Notice how your single-player worlds are saved in region, DIM1 and DIM-1 folders. Each of these folders is your dimension.
Multiplayer servers saves each dimension in its own folder, while the game (single-player) saves it as a whole folder of its own.
So, what you want to do is copy the DIM1 (Nether) and DIM-1 (The End) into the folder with the overworld dimension in it (level folder; as it is called in your screenshot), and then you can put your level world folder straight into your saves folder, in the Users/[Username]/Library/Application Support/minecraft/ folder, which then will run perfectly fine with all your dimensions intact.
Player inventories, locations etc. are stored in the overworld folder (level), so all locations will be preserved. (Means if you were in the nether, you'll log back on into the nether, or where the level.dat says you are)
You should end up with a file directory like such:
...
- local
- ...
- minefold
- ...
- level
- data
- ...
- DIM1
- ...
- DIM-1
- ...
- players
- ...
- region
- ...
- uid.dat
- level.dat
- level.dat_old
- session.lock
Note: "..." means things not included/not important.
The DIM1 folder contains data for your Nether,
The DIM-1 folder contains data for The End and
The region folder contains data for your overworld.
Everything else, you do not need to touch.

Make a commandblock loop which for every world sets the gamemode
use this command
for X you can ether fill in 0 for survival, 1 for creative, 2 for adventure, and 3 for spectator.
here is how a loop is made: you can put an lever on it to turn it on and off easely.
