3 - My big question, how do I attach the fence to galvanized corner, brace and H posts? It's not like I can hammer fence staples into them. Is there something available that will make this easy? The only thing I've come up with so far is to wrap the fencing around the end posts and secure it to itself and to use wire to attach it to the H posts like I would a T-Post.
Aluminum or light steel wire in short precut lengths can be purchased at chain link fencing suppliers such as Master Halco. These come in several lengths and are pre bent on one end so they look like a check mark so to speak. These will work well on the corners. They can also be used on the T post or you can use the normal wire ties on the T post that look like a W sort of. The aluminum ties can be bought in light residential grade so you might want to avoid them for your purpose and get the commercial heavy duty ties. We use them on chain link fencing up to 10 feet tall so i think they will work well for you.
Zip ties that are metal can also be bought. Yes metal ones, they are usually stainless steel. Can be tightened with pliers for a small job or a special pliers / gun can be purchased that stretches them and cuts them off all at the same time.
