I like having projects to build, especially when I get past the stage where I need to go down into the earth to gather resources. Once I have my power sorted and my inventory management sorted (literally) I tend to get bored.
I'll update my OP with a list of suggestions so others can have a checklist to push away the boredom as well.
1) automated forestry tree farm -> charcoal processing -> steam boiler -> lots of power with no maintenance
2) Automate everything with ComputerCraft
3) Research and create everything in Thaumcraft
4) T5 Spawners for all mobs
5) Use Extra Utilities to create an auto-compressing cobble storage system
6) Use Jailer's Safari Nets to capture one of each creature and build a zoo
