The springs should last for a long, long time. Also, shocks these days tend to last for a long time, so I don't think you need to worry about them, unless you regularly drive on some gosh-awful roads.
Others will chime in, I'm sure, regarding your other questions. Good luck and go for it. You won't regret going with Swifts. I smile every time I look at my car now. It's the way Nissan should have made it to begin with!
