The 16025 should be enough, but I would probably get the 28025 or 25035 (for more voltage in the future) just because I like overkill.

As far as rims for the phaltlines, they make 2 styles "blast" and "tremor" available in chrome as well as black and white I believe. The phaltlines are a bigger inside diameter than 40 series IIRC, so I doubt you could use them on 40 series wheels. You will need 17mm hexes to run those HPI wheels as well.
