as for the sanding, i would recommend scotchbrite pads to prep the metal, and a chemical paint stripper to remove the clear you have on it...
someone else said it's not necissary to clear the rim, that is true, but bare aluminum will oxidise and look like crap... i would use a varathane type product, if you can find it, it is illegal almost everywhere in canada (except my province) spray paint lacquer, with UV protection... i used just a regular lacquer on my license plate bracket on my bike, and it's solid as a rock, did about 8 coats on a wire brushed piece of steel, looks almost as good as chrome... (i have pics if you are interested) and no rust to date, this was just over a year ago, and no chips at all... the lacquer dries as hard as diamond... (i think varathane brand advertises their "diamond solid finish" or something like that)

If it is not too late here is my thoughts, IMHO...
Get the rims sandblasted by someone that you know will do a good job.
Sanding is OK but it just does not make an even finish and there are those corners and edges that always get left out.
Wipe the rims with a Tac Cloth and something like Prep-Sol, a pre-paint solution.
Spray the Rims with DuPont Metal Etching Primer, two nice coats, the second can be applied almost immediately.
Let the Etching Primer dry for a couple of hours minimum, maybe longer if you can and in a heated room, garage or in the sun. (this allows for the etching to take place)
Then use any of the DuPont Paint Products, regular enamel, wheel paint, which ever one you want get it done.
Spray with a Clear Coat BUT, read the instructions on the paint can that you painted the rim with; some paints need to have the clear applied within hours, some within minutes and some need the top coat scratched with Scotch Bright so the colored paint will need to dry really well before scuffing.
The sand blasting will cost a little extra but in the long run will look the best, more even, no scratches from the sand paper, an over all better job and finish.
Etching Primer is a little pricey but well worth it, don’t skimp on it.
Using all DuPont Paint Products makes sure of compatibility and adhesion.
Luck to ya.
