I also made my own 1.6.4 modpack with a pretty decent list of mods - pretty much everything me and my buddy wanted. Have been playing this world for 3 weeks now and it's very stable.
 
The process is pretty easy, once you know how to do it.
 
1. Install vanilla Minecraft. Go into profile and change to 1.6.4. Re-start and play MC at least 1 time to force it to download/update.
2. Install Forge 1.6.4 installer. Go into vanilla MC launcher and change profile to Forge. Run 1 time to force it to download/update.
3. Now, the long part. Go and find the mod .tar and .zip files. Put all of them into your .minecraft/mods folder. After installing all mods. Startup Minecraft, use the Forge profile, and start a single-player world. Work through the ID conflicts. To fix these, pick unallocated (guess at random ones if you have to) and modify the files in .minecraft/config .
 
Eventually, you will work through step 3 and get a successful boot without item/block ID errors. Now you have a working mod/config set. Copy the mods and config folders to the server.
 
For a server setup, it's similar to 1 and 2 above, but for the server versions.
