Two factors to consider:
1) Done properly, it is good to run analog and digital components on different lines on the same phase of the fuse box.
2) How much current does your amp(s) draw? If it is a high power model, it will benefit from having its own 20 amp line.
If you want to isolate your analog equipment from the digital (without a power conditioner) and your amp really needs its own dedicated 20 amp line, then you will need 3 lines!
I have not used the Belkin units but I strongly suspect that you will find after installing dedicated lines that your system will sound best without them (it probably will sound better without them now).
If surges are your concern, then use the blue whole house unit that has been recommended numerous times on Audio Asylum.
If you must use a power conditioner (don't just assume that you do), you are right to only consider the SOTA: Synergistic Research Powercell 10SE, Audience aR6-T, etc. You would want to run all of your components through these for maximum benefit (only need one "strong" 20 amp line).
Running two lines is indeed not significantly more expensive that running one as others have said. If it works out the your system works better through a single line, you really haven't lost much money.
The trick to eliminate ground loops is to run all of the lines powering your equipment to the same phase (leg) of ground in your fuse box. It is also a good idea to isolate all of the "noisy" lines on the other phase from your equipment. Your electrician should understand this readily.
Minimizing ground leakage as perfectly described by Inline phil is also a worthwhile exercise.
