You might want to think about getting some forged rods as well. Basically, all you will need on top of your HRC stage 2 is a set of forged rods and pistons(get lower compression pistons) and total seal piston rings. Thats pretty much it for building your internals. Thats all that the HRC eclipse has and there are many others on here with that set-up. You should be fine into the 11's with the built bottom end. But if your gonna fork out the cash to do the engine rebuild ($1100 at www.howellautomotive.com) then you might as well dish out another $600(fuel support) and start boosting heavy. All the rebuild will do is strengthen your motor, you will need bigger injectors and an AFC or some other type of fuel controller to safely run any higher than 10psi. That is going the safest route, and is what I'm in the process of doing right now. Oh yeah, being able to boost 15psi will for surely be a lot more fun than 10psi!!!!!
