The fact that your DB presses are so high compared to your BB work tells me that you're probably not using enough range of motion. Don't be afraid to go down in weight and do it right. Slight inward angle of the forearms is actually normal on any DB presses, so don't worry about that.
As for rows, there's a reason hardly anyone does them correctly; they're hard and you can use a lot more weight if you do it wrong. Stick to your guns. Flat back, just a little body movement, pull with your elbows and squeeze your back at the top.
Yep, better now than later. I do have to say it makes DB shoulder presses feel weird to do. But I remember when dips and deadlifts felt weird to do too :P. Yep, my DB is so much higher than barbell but I have a feeling even after I conquer the range of motion, it still will be higher than BB.
