I am ordering a spec stage 3+ kit with the bullet aluminum flywheel for my 335is but I don't know if I need any extra bolts/bushings/mounts and where to get them. If there is anything that I should replace while the trans is out please let me know.

Bolts on the bell housing.
Bolts that secure the flywheel.
I believe ECS has a bag of necessary goodies for like 200 bucks.
Clutch delay valve defeat.
That 10 dollar clutch pedal stop.
Short shifter now? Maybe an illuminated shift knob?
Change the tranny fluid / oil.
There are more. Been down this road, want you to do what you'll end up doing later for zero more labor cost as everything is out. Get it all and dont mess with the tranny for 50 k miles.

Why the aluminum flywheel? Asking as most go with steel as it is not as noisy.
Do you really need the 3+? If under 600 whp, you might consider the more streetable 2+.

New pivot pin. I bought a brass pin. Think about the 'while I'm in there' parts as well. I bought a new flex disk and installation kit.

There are a number of threads on this topic where people asked the same question; try searching for those as some of them quote part numbers as well.

In addition to the bolts and brass pivot pin as mentioned above;
Shift bushings - Best to upgrade with polyurethane/Teflon
Pilot Bearing
Throw-out Bearing
Clutch Fork
Throw-out Guide Tube
Transmission Input and Output Shaft Seals
Rear Main Seal
Flex Disc/Bolts
Exhaust gaskets/Bolts

In my opinion FCP Euro is the best resource for these kinds of parts. They currently have the lowest price on the bellhousing/flywheel bolts(just bought all this stuff last week). And everything they sell has a lifetime warranty.

Another thing I've found that helps a flawless install is an aluminum alignment tool. The plastic ones always have a little more slop to them and can sometimes break off.
