New to forum: 2000 Boxster with 109k miles

[Frogeye]

Hi all I wanted to introduce myself to this forum. I recently inherited my brother's 2000 Boxster. It's blue with tan interior and has 109k miles on it. It recently had new rotors/pads, brake fluids, oil separator, new tires, oil change, and a new air filter replaced.

It needs:

New spark plugs ( what do you recommend )
Center Engine motor mount with bracket
Transmission mounts

Where is a good place to buy parts ?

I plan to do all of the wrenching myself.

Thank you for your advice in advance.
