I don't know of a GM tool to remove cooldown other than the client commands but this is not a good idea. You will be able to spam skills far faster than you should and it will kick you like it is.
Getting d/c when using warps is always the same thing, the warp data in your client encs does not match the warp data in the server scp files. The most accurate patch so far is the one Lost-Spirit posted.

As far as i know nobody has working GG files because of the way GG works. We can't use the newest files because the server lib is too old to understand them. We can't use older files because even though we can get them the most important file (update.cfg) cannot be found or created. Without the right version of that file GG will not work.
