The ME flight time could be unique to our class since it was such an abrupt thing. Speak to your recruiter. I wish I could give you more info but I'm just sharing our experience. YMMV.

You cannot flight instruct once you get hired. Maybe if you do it for free? If you look at your CFI cert, it says it must be accompanied by your commercial cert... so if you're exercising the privies of your commercial cert.... that's a grey area. Up to you... Somebody smarter than I could prob chime in and help. Personally, I wouldn't risk my future with YX for a few extra bucks.
