With all the feedback, suggestions and help from this community, I'm confident I can do both jobs. I think this summer I'll knock out the leaking valve cover. Then slowly do my research and buy the tools for gear change and bearing/seal replacement for next summer.
I have to take it easy...if I lock myself in the garage the wife will make the garage my permanent home. I've already done the TBU, fuel filter, lift and swapped tires and wheels. The muffler delete just about pushed her over the cliff...
Thank you all the help. Great community!
