Don't fret...
First things first, is your room controlled? If not, get crackin'. Take care of some of those early reflections, and any extraneous noise. If your room doesn't sound "warm, round, sweet, or whatever," acoustically, neither will your vocals. Concentrate on your mic technique. Control your siblance and your fricatives as well as your distance in relation to volume increases and you decrease your need for a compressor and any reparitive processing.
Try singing into the TLM103 about 6" away, 30deg (or so) off axis, pop filter about 1" away from your mouth angled away from your mouth towards your nose a little. IIRC the TLM103 is cardioid only, so you don't need to worry about other patterns.
Set the 386 drive at about 11:30 and the output to whatever is getting you good level. As you are singing, move around the mic a little, this will help you find the right axis that sounds best on your voice.
Oh yeah, engage the lo-cut on the mic or the pre and see which one sounds best. You don't need those frequencies.
Add salt to taste.
