The threads on galvanized pipe are tapered and intended to seal against water leaks rather than to add rigidity and will not go in very far. Use two pipe wrenches to snug it up. Or better yet, switch to the easier to use fence rails that don't require tools to setup/take down.
10' will work, but longer gives you better tarp options and additional flexibility for setting up hammocks of different styles and lengths.
