The seals sound like they will work just fine, expecially if the rubber part of the seal looks simular to the original ones. Take your time.
Oh, by the way, be sure to check the bearings for any metal flaking or heavy discoloration, either of which are reason to replace the bearing.
Do not wash the old bearings, just use a claen rag to wipe as much of the old grease off as possible. The reason for not washing them in solvent, is that its hard to get all the solvent out, and the solvent is designed to break down and remove the grease.. so you can see the problem with that.
You'll do fine
