Adventure Map Recommendations?

Anyone have recommendations for existing plugins for the purpose of converting various single-player adventure maps to multiplayer maps?

Here are some concerns that I don't have great solutions for yet:

1. Map needs to be reset after use (many 1-time use machines/switches)
2. How to handle groups of people (and preventing others from joining while a session is underway)

Here are some known solutions:

1. ServerSigns plugin for use to create items to give players which can have cooldown which allows unlimited number in a group to collect the same loot.
2. WorldGuard plugin to prevent players from placing/breaking blocks and prevent explosion damage to blocks
3. CleanRoomGenerator plugin to ensure world does not generate any more land, especially if maps were from older land generators (like Minecraft 1.0)
4. Ancient Gates plugin can be used to ensure any portals that go to other dimensions will go to the correct location. If the portals don't link up like they used to in older MC versions, this can be used to re-create the portals to teleport to the original location

Thanks,

I have found these plugins but cannot make them work:

Anything else out there that might work? Doesn't specifically have to be for adventure maps, anything that handles party systems and world restores might work.
