Congrats, you're gonna love it. It's a suitcase of goodness.
I'd grab a bunch of small containers to keep all the hardware in. They're marked and referenced in the instruction, it's easy if you have all the A, B, C, D parts, etc in cups or something instead of rifling through bags.
Also, a few years back Tamiya started using ABS on some parts like road wheels (don't know why, the polystyrene holds up great), so pay attention. Again, it's in the instructions and marked on the sprue (PS, ABS).
If you're not familiar, normal modeling cement is for PS and won't hold ABS. You'll need Tamiya Extra thin, PlastiWeld, Tenax or any MEK or methyl chloride based glue.
