why are you exporting to ASC format first?
LithUnwrap used to support pre-4.3 COBs - pretty sure 1.3+ supports 4.3 as well
i've not used trueSpace in ages - so i can't remember where the control is ... but a flipped face is one where you can see the backface - its kinda like an addition face living in the same space as another, you can either delete or flip (exporting formats oftenly causes from trueSpace unless you trianglate them first)
attention is kinda torn right now, i'll go into a deeper explaination later.
