Default 99 Accord Exhaust System Recommendations

What a fantastic car this has been! After 116K, I finally get to work on it. It's throwing a catalytic converter fault code, and I want to renew the entire system once and be done with it. I'm asking the forum to check my assumptions, give me installation tips, answer a few questions and recommend parts and sources.

I assume I'll want to change out the manifold gasket, but the manifold typically will not need to be replaced. I'll want to replace both O2 sensors and all of the other gaskets. The nuts will spin free without a hassle, especially the ones connecting the downpipe to the undercarriage, ahead of the cat. The heat shield(s) will need to be checked for tightness but typically will not be damaged and can go another 100K. The new cat will come with upper and lower heat shields. The rubber hangars should be replaced because I'll probably damage them slightly on removal. I can reuse all of the locking nuts. I should install the new components front to back, connecting as I go. Look good?

I don't have a lift, so how much ground clearance will I need to wrangle the pipe out and in, over the rear axle? Will 24" be enough, for example? Should I use Loctite anywhere, everywhere?

I want a perfect fit and no hassles. Genuine Honda parts or secondary? Stainless? Any particular secondary that gave you a perfect fit?

Many thanks in advance for good advice: I appreciate it!
