Hi paynez,
I think you have a nice little set up there and you have bought wisely.
The trouble with advising you here is that I really don't know what the standard of your musicianship is. So I can't say to you to hire a session drummer etc.
It is quite possible to record acoustic guitar a vocals well in almost any space such as a home studio but drums are always best done in a propper tracking facility. Things like low ceiling, room reflections and lack of experience tracking drums really lets down the sound.
If you want to track drums and can play I would suggest that you buy a Roland Vdrums set such as the TD3 system and linking it by midi to a plug in call Drum Kits From Hell Coustom and Vintage. This runs off a Native instruments plug in engine and can be run as a Rewire plug in with your Protools LE Rig. But if you are good at programming drums then you could go down that route with Reason. Professional sound percussion and drums are a big help in making a release quality Album at home.
I really don't know what your ear is like for mxing. I know many wonderful musicians who have excellent ears for music, pitch, intervals and tuning etc but they can't mix or choose pre amps and mics for their voices etc. People tend to pick things that are more forward sound and louder sounding rather than hearing into tone etc. So my advice is to read the Studio SOS articles at the
www.soundonsound.com web site and look for the advice they give for recording acoustic guitars and vocals.
People talk about the RNC as a great compressor but it is in actual fact a coloured sounding compressor so be careful tracking through it.
If you want to take your equipment to the next level then I would get a pre that is neutral but good for acoustic guitar and vox as it will sound great on most things if it can be used for that purpose. Try a DAV Electronics BG1 pre. I say this because I really don't know the RNP. Apart from that some more good mics will make the biggest audiable difference. I think electric guitars and bass sound good through Tech21 Sansamp products. And lots of guys like to put their drums and percussion through them also. You can buy them as a plug in for Protools so a nice DI into your 002 and then use the plug in and you are away. But The actual Tech21 pedals are cheap and well worth the money just straight into your 002. They can really add rich harmonic distortion/speaker emulation to your bass DI tracks wich is another thing to acheiving a pro sound.
Don't be afraid to take your recordings to a local facilityto you who are working with local artists and who've worked on cd's you've thought are good for the mix.
Another thing about recording acoustic guitar is that the guitar itself is responsible for the earthy sound you describe in your post. As it happens the singer in my band has an old washburn guitar with a solid wood soundboard that has aged well and your guitar just might not be able to produce that sound.
Something you should know is THE SOUND AN INSTRUMENT MAKES IN THE ROOM IS HOW IT SOUNDS! So if the source ie your voice or the acoustic guitar etc isn't making the sound you want then you had better consider training or buying a new instrument. Don't try to rewrite nature ie the sound that is being made. Listen to it critically. If it is very close to the sound you want or is actually making the sound you want then all you have to do is capture it. Tracking with the idea of mangling the sound into something else almost always sounds like dogs balls and takes the quality of your recording into the amateur.
Anyway Happy New Year and good look to ya.
Peace'
