Wayne - As to the first, I don't really see a need to do the "rough collar" in front. The false front does serious damage to shots played short, or shots that are run up inadequately. Putting rough in front would merely act as velcro for misplayed shots, with a less difficult recovery. In addition, the hole currently allows a run-up approach, which is rare (and I've had to play my share out of the right and left trees...)
As for new tees, new ones along the line of play, like 4, 8, 11 and 17 are doable, but just not an incredibly high priority. The bones of the golf course are solid, and more will be added by subtraction (trees) than anything else.
