When it comes to boosting the ratings of a player on the DL, does it matter if he is on the 15 day DL or the 60 day DL? I do have a high Medical and Training budget.

I put a player with a short term injury on the 15 DL and he got a recovery and a nice boost in a couple of extra categories. I can live without him for a bit, so if I leave him on the 15 DL, will I see the same ratings boosts or will it only work if they are on the 60 DL?

I think you would need to transfer him to the 60 day DL to get a further boost. Once the DL icon is green, no more boosts.

I thought you could still get bumps once it turns green. However, it's hit or miss.
