Alright. After spending around 30 minutes in solo approach mode I think I've figured it out for you. When landing the CRJ, use flaps 30 and NOT 45. When landing, you want to aim for around 120-130 knots. Once you touchdown after your flare, the nose will want to pitch up because of the old flight model of the CRJ. To counter this, simply push the nose down right as you land.
During wind conditions, follow these same procedures plus the crosswind landing tutorial made by Mark Denton. Please note that since it is an old model, the CRJ is a bit "sensitive".
I did not encounter any issues with one wheel touching down first during my testing. It might be the old model. But hey, use that to your advantage in crosswind landings.
