interactive startup..

i have used the interactive startup in the past on my system to skip wireless mode when I am somewhere out of range of the internet and and have only the 2hrs battery lifetime and no place to connect my laptop to the mains.. i usually skip isdn and networking. what I would like to know is how would put to use the inetractive startup to more efficiently run my system as in the example above.. . more precisely if i were to use the interactive startup more often and for other functions how would I most benefit from using this..
cpuspeed for example... if I am on battery and not using wireless would skipping cpuspeed maximize battey life?
any feedback welcome

AIUI, programs like cpudyn, cpuspeed, etc help increase your battery life by reducing your processor power draw (speed) when not performing cpu-intensive tasks. You probably don't want to skip that one.
