No, all that stuff is for the mikes. Plus, on the whole, I don't really like using the AGC or comps for recordings. they just pump and breathe just a bit too much for my tastes...
Use 24 bit recording, and you can record at VERY low levels without losing any detail in the quietest passages. I rarely like to set my levels so even the VERY loudest part hits -6db. Track lower than that, then normalize afterwards.
I think I read somewhere that a 24 bit recording at -22db peaks gives roughly the SAME dynamic range as a 16 bit recording at Odb peaks (tough to do without overs!

) so you can be very conservative in your level setting, and avoid ANY overload possibility, and still exceed 16 bit's theoretical range.
When recording live, it's my goto bit depth. Then I NEVER have overs...
