For your starter check to make sure your battery connections are good and clean and that you are getting good power to your starter. The bendix drive on teh starter is the gear that spins up to engage the starter to the flywheel, and if it doesn't get good power to the starter(about 11 volts during cranking) it will not push teh bendix up to engage it. Next try and spray a small amount od lubricant onto the end of the starter shaft where that bendix slides out. Be VERY careful here as some of the bendix drives use a rubber coupler and lubricant can cause them to slip. So just a small amounto on just the shaft where the starter bendix slides is all. I have seen them get rusty in there and the bendix will stick part of the time. The most likeley causes for your problem is either a bad solonoid, poor connection at the battery, or a sticking bendix on the starter shaft.

And as for the leaky primer solonoid, it is easily repaireable. Part number 18-7044 from this site includes all of the pieces to re-seal it.
