Vibration in my clutch pedal at 68k miles

I believe the throw out bearing is bad on my 2004 330i. I just bought the car. Its a ZHP with 68k original miles.

I believe the bearing is bad because the clutch pedal has a vibration that is RPM dependent. I can't say for sure yet but I believe the vibration goes away once the car is warmed up.
I am not hearing any noise coming from the bearing but the car has no muffler so that could be masking it.

Do you think I am correct about it being the bearing causing the vibration? That is just the best guess I can come up with from my research.

Assuming that it is the bearing and I am going to have to pull the trans and replace it, what other things should I replace while I am in there. I started adding up the list of parts but
just wanted input on what you would change and what you would leave alone considering it only has 68k miles.

The things that immediately came to mind were,

Guibo
Center Support Bearing
Rear main seal
Pilot Bearing
Clutch/Pressure plate
Flywheel
Obviously t/o bearing

I don't want to go crazy and replace things that don't need replacing but I also don't want to have to pull the trans again in 30k. This car is about to go from a 2 minute commute to a
45 minute commute and I want it to be 100%

Any input you guys have would be much appreciated.

Wish I could help, but I'm not familiar with this issue. Other, more knowledgeable members should be along to chime in soon.
