Hey Brad,
Personally, I'd skip a drum mic pack all together. You can do better buying individual mics (though it will be more expensive). Just because it says "drum mic package" doesn't mean it's great at recording drums.
Regarding acoustics, my favourite solution when you also need portability is to create some gobos consisting of a wood frame, filled with rigid fiberglass (Owen Cornings 703 or equivalent) with your choice of breathable fabric staples on the front. You can check out some of what I've made here:

You will also want some kind of wall mount absorption panels similar to what Ethan makes with his company, RealTraps (

You really need a multi-faceted solution...some bass traps in the corners, acoustic panels on the walls, and some gobos to create smaller recording spaces. If you search around c7sus created some great tall gobos that can be used to in effect create a modular vocal booth. Read the threads around here...this stuff is covered a lot.
