I may be just anal retentive, but i would change the strings 3 weeks in advance and beat the hell out of them.
I've never had to do trust rod adjustments, even from using .090 to jumping to .110....I was probably blessed with a good bass and good set up
It's really at your own discretion, I usually do action and everything, and if the action is too high, that's when i start doing rod adjustments...but this is something i've only done on gutiars, that is, they're more tempermental. But it wouldn't be such a bad idea, beat up the strings, set intonation, and if a rod adjustment is necessarry, go for it...
just remember, lefty loosey!
