Stay with the "flimsy" gear a bit longer. There is stronger nose gear out there but if you land wrong on it you will rip out the firewall every time. Easier to replace the wire leg for now. As for the floating, try changing props. Reduce your pitch by a number or two. example: if now a 10x6 try a 10x5 or even an 11x4 if you have prop clearance. This will let you slow down better. Also make sure you are getting your idle down where it needs to be.
