It's a redpower bug. Backup your world. Then try deleting "...\server\<map_name>\players\<yourPlayerName>.dat" This will remove all the items you have in your inventory.

Possible? Yes. Practical? No. Unless you have a huge amount of time invested into an old world you are better off making a new one.

What do you mean by "when I try to put my tekkit lite single player word in"?

On a Windows 7 Machine, your logs will be in these locations: C:\Users\<your_user_name>\AppData\Roaming\.technic\logs C:\Users\<your_user_name>\AppData\Roaming\.technic\tekkitlite (called Forge Mod Loader) Grab the most recent of those files and post them on http://pastebin.com/

Post your log files. Have you modified / added any mods?

It should not be using that much memory. What are you using to determine how much memory the server is using?

Also be aware that some mods may technically require you to obtain permission if you were to alter their files and redistribute them.

The world has likely been corrupted. Redpower frames have been known to do that. They don't play well with other mods. You will have to revert to a backup. There is a small chance that you could recover the world if you used the beta version of mcedit and removed the corrupted blocks (in this case it appears to be related to a cover likely connected to a frame). I can't walk you through how to do that, and in reality it would be a major pain and would require you to be semi computer savvy.

They should be located somewhere in the correspond mod's jars.

I'm going to have to agree that the problem is with the host. I don't have too much experience with finding Minecraft hosts, so I can't help you out there. Perhaps you can find a good one by word of mouth and seeing what other people use.

What exactly are the specs of the server and how many people play on it?

If tekkit lite will be updated (which I hope it will), it will have to be after redpower2 is updated (which may be a while...)

Please post your client and server log files using pastebin.

I don't know. Perhaps several vps's share the same network card. You could ask your host if they could look into the issue.

Try disabling/removing forge essentials and dynmap and see if that helps. Did you run that test during server primetime? A ping of 350 ms is still bad.
