The 2 xlr inputs are defaulted to - active pre-amp inputs - which can be 
over-ridden by changing the jumper(s)
on the 1010LT. The other inputs are designed to be used with a mixer - 
using direct outs  or with mics(or anything)
using a direct box  or pre-amp. While you can plug your guitar into one 
of the - preamped XLR connections , a better approach would be to use a 
really good mic to capture the "acoustic" sound of the wooden 
instrument. That totally depends on what you are wanted to hear and - 
Basically - subjective.

1st version, leave the jumpers in default - use inputs 1  & 2 (the XLR) 
with mics and mic your guitar - RECORD it.
2nd version - change jumpers on card from pre-amp  position to 
line-level - use a mixer( mixing board)
plug all instruments /mics into physical board - use direct outs from 
board to inputs of soundcard. you now have a studio set up.     Utilize 
the physical  board - not so much as a "mixer" , but it does give you 
greater control of signal/gain . you would use envy24control as your  
level monitors , and the mixer in ardour to finesse and also to control 
the mastering later using jamin  etc.

Initially by adding the physical "mixingboard" into your system setup , 
does add one more element to potentially mess with you,you can  do this 
. Like you said, backing out and sorting 1 variable at a time makes it 
clearer in ones head - what is actually going on.
I find the best signal to noise ratio looks something like this  - the 
sliders on the physical "mixingboard" set to the lower side and the 
sliders on envy24control to high or max  - allows for the best signal to 
be recorded.
this is strictly my opinion- not based on engineering etc. anyone with 
more knowledge might challenge me and I am ok with that  - I am always 
up for learning . These are things that I have figured out through 
reading and trial and error.

good luck . - have fun !!
Matt
