With the pump gas heads you run premium fuel from any gas station. As far as aftermarket parts go the 440's already come with a SLP ceramic pipe from the factory and you can't buy a can for them. These sleds pretty much are ready to rock from the factory. The only things that you can add that would make a difference would be Studs, a Clutch Kit, and maybe reeds. Either in 03 or 04 The 440's started to come with VForce reeds. So you may or may not already have them.

Yup. And if you still have the stock race gas head, there is no way octane booster is going to bring your gas up to 110. Run real race fuel.

You should have to pre mix all the time, no oil injection on them.

You will have to jet for the temps with the 440. The ones I have rode get pretty finiky with 10+ degree temp changes.

Assuming you are at sealevel The polaris Pump gas jetting chart for a 2003 says -23 to -34 degrees celcius use 360 Jets and from -34 use 380's.

if its your first take youve run it it do 32:1 and then add some more oil just to be sure and for the first little while check your plugs nonstop, just to be sure.
