You should add NEI Plugins as well (Different from NEI Addons) because it adds advanced integration for Thaumcraft and Forestry. I must also add that IC2 would be a good idea because Forestry does not require it, but uses it if its in (that or Mekanism, but IC2 works better with Forestry). Also, make sure every mod there is server-side (Shatter is not) because it can cause the crashies. I know most mods are universal, but there are still some exceptions. If you have any problems I could help. Making a Technic Pack wouldn't be a bad idea either.
