Heya Logan,,
on of the best tools to use to clean piston ring gaps is..... a broken piston ring!!
if it has a shapr edge (better to use a stone and hone it flat so you don't score the groove), and remember to use gloves, cos the edges of those rucks are feckn sharp!
why don't you want to pull the rods off the pistons?
as for U/S bath, there should be no dramas.. what you need tho is a solvent that will remove the grease/oil/ and carbon...
before you chuck it in the bath, get some WD40/RP7/stuff, and spray the carbon'd areas.. i find that the carbon will easily lift off the next day.
removing weight is interesting.. have to be careful where you take it from..
what you SHOULD do, is remove the rods, and balance them for total weight, and for end to end weight (ie each end is same weight), and same for piston/pin assembly..
i balanced mine all to within 0.1grams which is overkill.. the TOSCO/TRD 3K manual i have said 1 gram..
i removed weight from around the big end caps, and also from the inside of the piston pins... i would not recommend you do this.. instead ask someone who knows  ie an engine balancer 
weigh them first and decide if they need doing.
Cya, Stewart
