so my server is gonna die and i will never find the suspect
It's time to scale your WorldEdit permissions back, or deop these players then.
You might consider logging player commands with the Commands Logging plugin. You'll at least be able to track WorldEdit activity. The plugin is outdated, but still works with CB1060.
You probably want WorldGuard if you don't already have it. You can protect areas, disable TNT/lighters, block actions, setup notifications, and more.
You might considering a logging plugin as well, like LogBlock or Hawkeye (soon to be merged). With these plugins you can roll back areas prior to the griefing.
Iinstalled permissionsEx and now when I try to join my server it says "can not connect: connection refused". And also, how do I set up user permissions? the group and config.yml are empty.
The error you're getting has nothing to do with Permissions. It indicates the server is down, the listening port has changed, or just an inability to connect to the server.
The PermissionsEx wiki documents the configuration clearly. That's a good starting point.
You didn't happen to put an IP address in server.properties did you? If your internet service went out, you likely have a new external IP. Make sure you leave this value empty, then give outside players your new IP address or use a service like DynDNS.
So you paid a server that can run 200 players, without any active ones? Rent a 20 slot server first, and see if it works.
I believe this is a privately hosted server with decent bandwidth, but your point is valid. Opening a 200-slot server to the world without a clear theme, no logging mechanisms, no hierarchical permissions, and without whitelisting, is ripe for failure.
From the server machine, you should be able to connect 1) localhost 2) the local IP address, or 3) the hostname. If you're connecting over a LAN, then you'd typically use that same IP address or hostname. For external connections, you need to port-forward, which is well documented in these forums.
The permissions themselves aren't really any different, they were simply moved into bukkit so that there is one standard interface for developers to hook. You have your choice of permission managers now (bPermissions, PEX, and PermissionsBukkit, to name a few). I prefer bPermissions myself, for simplicity. Have a look at the plugin threads for each and decide which one suits your needs. There are converters available for the old 2.x/3.x files.
Here's a snippet from my private server's bPermissions world.yml file for reference:
When you say you had to 're-do' the entire server, you mean you literally wiped all of the server files and started from scratch? Obviously something changed between then and now. Comb through your server.log file for clues. Post any errors here if something isn't clear.
I've been running a server since January, with an average of 35 plugins, and up to 10 simultaneous players. Memory usage has never gone beyond 2GB, and averages 1.5GB. You're seeing 8GB?
Open Task Manager, go to the Processes tab.See how much memory java.exe is using.

Good luck!

Have you started a thread on the bukkit forums?

As far as other plugins, that's really dependent on your needs. Here's the bare minimum I'd recommend for a public server:
McMyAdmin for server management and backups. This is a web manager for minecraft & bukkit servers. It's on sale for $5EU right now.

For bukkit servers, there are a number of plugins that allow you to reset the spawn in-game. With these, you can set a precise location.

Were you able to backup previously, or is this your first attempt?
Also check McMyAdmin-Errors.log for more information.

Technicall you can use any port from 1-65535, but for simplicty I'd stick with something like 25566, 25567, etc.
