I'm afraid your desires are out of my league. I don't believe a sling, bayonet, or heat shield (if you have one on the gun) are desireable on a home defense gun. At any rate, you don't have to sacrafice any of these with the mount. The bayonet should sit under the mount if you attach it forward of the bayonet mount. If you don't have a heat shield (and why would you) then you can mount it in front of the fore-end and behind the bayonet lug.
If you look at the TLR-1, there is a switch assembly at the back of the light. To work with a remote switch, this must be replaced with a new switch that includes a socket for the remote switch.
Finally, mounting the flashlight on the left side of the gun is a matter of preference as it is on the same side as the sidesaddle and means the overall gun is not as wide. Two other reasons. First, the shadow from the barrel/magazine is on the opposite side of the gun and doesn't obscure your target as much when you have the light on. The second is that when you "cut" a corner, the wall doesn't obscure the light as much... technical, but I've done this before and it works better on the left.
May I plug my belief that a sling will just get in the way and is counter to a gun that you need a light on anyways. The Bayonet is useless in any situation. Try to defend yourself in court if you had a fixed bayonet when you held somebody at gunpoint. Finally, the heat shield (if you have one) is less than worthless. It adds weight and bulk, scratches your barrel up, prevents mounting a flashlight in the right place, rusts, pinches your fingers, and looks stupid (my opinion).
Some other options. You can by a "Fab Defense" fore-end. It's marketed by Mako, made in Israel, and has rails for mounting your light if you prefer that. I didn't like mine much, but it was very well made. The other is a flashlight holder that'll go in your sidesaddle. Those seem kinda cheesy, but again, it's another option.
