new to the TiVo (roamio ota)

we just cut the cord (Dish Network) and after weeks of research I settled on the TiVo... It's everything we were looking for ! I do have a few questions....is there a way to turn off the "beeps" when changing channels or using the remote ?



Also is there a way to store my favorite channels ?



I did not realize when I purchased the OTA that I would not be able to buy the life time service....do you think will change down road ?



Thanks
