I don't know about the front sight, but as for the recoil pad, I replaced all of my stock remington pads with Pachmayer Decelerator and Remington (aka Sims Vibration Labratory) R7 recoil pads. These pads are excellent. They noticeably reduce recoil.
Now, all of my guns have synthetic stocks. As such, the pads on my rifles will not fit on wooden stocks. However, I would check with both companies and see if they offer similar pads for Remingtons with wooden stocks. If anything, you may need to do some work on the stock in order for the pad to fit perfecty.
