Where are you now on this project? I will be diving into there myself in the next few weeks, as my '95 alternator packed it in early this summer. It also has had an oil leak for a few years, from the wiring connection area. My solution, at the time of the alternator failure, was to buy a nice '96 that I found in Sechelt and ride it for the summer, but now I must get the other one repaired.
Since you are only dealing with an oil leak, at this time, you might want to ignore it and do your other work first, if just to get a little more comfortable with wrenching on the bike. Have you got the Honda Service Manual? BIG help right there. How is the alternator performing at this point? Is all the wiring and its connectors in good shape? Corroded and burnt connectors are usually what lead to the 28 amp alt failures.
My '95, owned since new, went almost 20 years and over 160,000 kms on the old 28 amper, but I also put very little extra demand on the system, with only 55/60W headlights and a heated vest. I'm thinking you might be well advised to replace the stator, if you intend to go in there anyway just for the oil leak issue.
Sit down before you ask your dealer to quote the stator price, but since you are likely sitting now, I'll tell you. Carter Honda in Vancouver quoted me $540.00! Needless to say, I went online and the best price I found was from Partzilla in Georgia USA at $302.00 US. Even with exchange and shipping, it is much cheaper and I also ordered a number of other parts and maintenance bits (brake pads, rubber cush dampers and inserts, etc) to make the extra savings with the same shipment. Ordering ST parts from the USA is definitely the only way to go. My last three part orders from the USA, not all from Partzilla, came to my door by Canada Post with no extra duty or customs charges attached. I expect my new stator and other stuff to arrive in a few days.
