I've been messing around with bedroom recording and music production too for the past few months.
Setup:
Interface: Focusrite Scarlett 2i4 (Was gonna get the 2i2 but the pad and the other extra features on the 2i4 were hard to pass up on. No regrets for $50 more.)
Mic: Audio Technica AT2035 (A foot or so away from the amp. I personally don't like the sound of closed mic'd amps pag solo guitar lang. Different story if it's for a full mix. An SM57 is on the wishlist.
)
Headphone: Audio Technica ATH-M50 (These are amazing. Definitely worth the money.)
Monitors: JBL LSR305 (Got this recently. Arguably the best monitors in its price range. Stellar reviews anywhere you look.)
DAW: Reaper
OS and PC: Windows 7 on a lowly dual core PC with 8 gigs of ram. Works fine without a hitch so far.
I mess with Guitar Rig and Amplitube too a lot when i'm bored. Endless tweaking and tone hunting. Definitely has its place too.
