adjusting suspension hard to do?

hey,
its glenn, i ride a 1996 zx6r. it has an aftermarket white power rear shocky with i think normal front shockies. the bike was originally a race bike till i converted it to road. Thus im guessing the suspensions set to extra erect (hard) when i use it as a daily driver.
How do you adjust the suspension?
is it hard to do or will it take long?
Am i likely to screw anything up and crash as a result?
thanks for any tips or advice. cheers. glenn
