Stop typing that long guide all of you have been typing for days! I have figured it out on my own and easily updated my server.
I'll post a how-to just in case anyone finds this topic in a search for the same answers.
In your server root there is 3 files and 3 folders.
config
coremods
mods
ftbserver.jar (!If you use MultiCraft, this might be named minecraft_server.jar)
ServerStart.bat
ServerStart.sh
1. First thing you do is BACKUP YOUR SERVER! I had no problems but user errors happen a lot.
2. Shut down your server.
3. Delete all 6 of these things from your server.
4. Download the latest MindCrack server files from the ftb site.
5. Unzip the server folder and it will have the same 6 things you deleted, only updated with 8.2 stuff.
6. Copy all 6 things into your server root directory. (REMEMBER IF YOU USE MULTICRAFT THEN YOU HAVE TO RENAME FTBSERVER.JAR to MINECRAFT_SERVER.JAR)
7. Now that you did this, start your server. You are now updated!
(Additional steps if you use MCPC)
8. Shut down your server.
9. Delete the ftbserver.jar/minecraft_server.jar.
10. Copy the latest version of MCPC into your root directory(it's a .jar file).
11. It will be named MCPCblehblehflippidyDoopWoop.jar (<- Something like that), rename it to minecraft_server.jar.
12. Start your server. You are now updated!
