Why would a railgun have less recoil? It is still subject to the same physical laws of conservation of momentum which gives full recoil. The only difference is that it doesn't have expanding gas from the gun powder, which would mean slightly less recoil without a gas vent, but obviously you don't have any gas to vent to mitigate recoil either.
This has already been partially covered, but basically, standard ballistics use a front-loaded chemical explosion which is resisted by the cartridge and/or chamber, etc. depending on the specific firearm. This creates additional recoil above and beyond the physically mandated action/reaction recoil. Gas venting helps mitigate this recoil. A rail gun propels the projectile via electromagnetism over the length of two rails. Since it doesn't use an explosion of any sort, theoretically you can claim it would have optimally efficient minimal recoil over a standard chemical ballistic. Also, as someone else stated, the force is applied over the length of the barrel, so you have less kick in the recoil as well. This second part, along with theoretically extremely controlled nature of the force being applied was my rationale for having easier to control recoil (-1 per uncompensated vs. -2 for standard heavy weapons).

I'm not completely sure I understand the idea behind this... explain?
Presumably explained above. The lack of the explosion, and the potentially open nature of the rails would act as a natural sound suppressor. I'm sure it would still make noise, but it would be much quieter then any chemical balistic. No muzzle flare either. Now the humming....
Of course, there are reasons rail guns don't "exist" in the real world, but this is SR bleeding edge tech, so we assume solutions were found

Arsenal page 40: FN-AAL Gyrojet Pistol. It exists.
Ah well, I don't recall them

, but I'm sure you could improve them and call it R&D next gen tech. An underbarrel nanite shotgun which shoots a cloud of targetting nanites with a linked AR display to select the nanite cluster you wish to target which then acts as a homing beacon for your gyrojet projectiles, giving you a Fifth Element style auto-targetting/hitting gun. Not sure how you'd work that with net hits to damage.... Just give the defender a defense die pool penalty probably.
