Usually when people say 'ME' on lifting forums they're going to be referring to Westside Barbell terminology, meaning Max Effort, which is working up to 1-3 rep max on a different variation of the powerlifts every week in that specific program. fyi
You're definitely on the right track, your strength levels aren't bad at all for someone who's only been training seriously for a few months.
Do you have a weight goal? Not sure where you live but here it's winter time and I always set a goal weight for myself every 'bulking season', that helps me get stronger faster and keeps me from changing my mind all the time. I imagine you're pretty lean right now and you said you're not too anal about your abs showing which is a good aptitude for a weightlifter within reason.
As far as programming, have you looked at madcow 5x5? Very good program for someone at your level, similar to starting strength but with more exercises. 531 would also be a good choice. To be honest I wish I would have used one of these programs and just focused on form when I was starting out, I'd be alot farther along by now. I actually think 531 would probably suit you since you can program your own assistance work and you seem to want to do that to some extent.
Little things I see right now:
-putting biceps on deadlift day is a bad idea. Personally I think deadlift day is a good day to amp up the hamstring glute and posterior chain work.
-I've actually done the back squats after fronts thing, felt not too bad but looking back I wish I would have just picked one and focused on cleaning up my form. Nowadays I like to either do back squats and then beltless fronts as assistance, or just fronts. After the main exercise it's all about working the muscle anyways, I wouldn't hesitate to change that setup if you're feeling tired one day.
-On chest day I would get rid of flies, but that's just me.
Good luck, hope that helps
