Not necessarily...try to figure out what spring rate different shocks are and find what weights are working well for people at your weight. It's not an exact science with these bikes because the options are limited. That's why I said pretty much anything is better. Changing the ride height could because it's easy to overdo it. An inch is a big difference. I put a gsx-r shock on my bandit and I'm considering lowering it slightly now. It raised the rear end a good inch and a half probably (wish I had taken some measurements).
The zx600 shock in my ninja is actually shorter than the stock 250 shock, but only slightly. However, it sags less, so the rear end actually has more ride height when you are on it. I still kinda want to try out the ex250J shock, but i don't feel like doing the work
I don't know anything about the links you speak of. There's no reason for it IMO, because the stock bike handles really well.
