I'd get the Vokey wedges 60/80/100yd. You won't need to ever change them. I think the Cally L95 is a better 100yd wedge, but not by much.
Go with the L86 or L89 3W, depending on which meter speed you prefer. Either will be a placeholder until you get to L99.
I'd wait for the L94 or L96 driver, again depending on meter speed preference. The L102 is the best in every way, but it's still a long way off from L94 and even L96.
You might consider the L85 irons. I found them to be a major upgrade from the L59s. However, the L97s and L100s are very similar, and both very good. If you get the L85s, you can skip the L97s and wait for the L100s. If you stick with the L59s, you can get the L97s and forget the L100s.
