Known things to watch out forIf you removed your clutch basket, there is a flanged washer and a locking pin behind it all that provides driving purchase for your oil pump gear. Failure to put it all back together correctly will allow your oil pump gear to move laterally out of engagment, scrapping your engine due to no oil pressure.
Next, there is a "big as the plates" thin ring like belleville washer (tilted washer) and some flat washers that pre-tension the clutch pack. Putting the tilted washer in wrong means it won't work right (causes an immediate need for tear down).
Soak your plates for a day in the oil you are going to use. Read "Recommended Oils" since you currently aren't using any of them.
Use a finishing sander to rough up your steel plates and get all the crap off of them. Medium coarse sand paper on the finishing sander, you will need at least several sheets as they like to tear up on you from all the sharp metal corners you go across.
And no, you are not the first person to take their clutch apart, but you are certainly the most inventive to date, certainly that's fer shure.
