Codeshare Flight queries

So i’ll be flying from Orlando to Dallas with American Airlines and from Dallas -> Doha -> Karachi with Qatar Airways. The thing is that I booked my entire itinerary through Qatar app(ss attached). I had some queries: 1) Firstly, i will drop my bags in Orlando and will i collect them at dallas and then check in again or will i directly receive them at my final destination (Karachi)?

2) is 1h 30m enough transit time at Dallas Airport to disembark from domestic flight and board an intl flight?
