Tire rotation is required because differences in tread wear, right? For a RWD, once you get some staggered (front and rear wheel size different ?) aftermarket wheels (assuming they would be willing since they are aftermarket...)you cannot do tire rotation anymore. If that's the case when the tires are getting old should they just get replaced by new ones directly?
Not trying to thread jack, but also for RWD, which tires are getting worn down more, front or rear? And is it always a better idea to replace all 4 rather than just 2 tires at a time? Sorry I really don't know crap

But yes, it's normally done on cars to insure even tire wear.
Typically on a 2IS because of the crap factory alignment you wear the front inner tires out first (often in half the time you do the rear tires). Proper inflation and a good alignment aiming for 0 front toe can help with this.
As to replacing, it depends... generally speaking you want your "best" tires on the rear of the car, so putting new fronts on with old rears isn't ideal... because better tires on the front means if the car hydroplanes it'll be an oversteer situation where the car is spinning out of control... whereas the better tires on the rear is an understeer situation when hydroplaning and it's much easier to control.
In a car with 4 equal wheels this is simple- when 2 tires are replaced you simply insure the best (newest) 2 are on the rear... and as long as you stick to the same brand/type/model of tire this should be ok.
But since the 2IS is staggered, if your front tires go first, you can't do this... so while you CAN just put 2 new ones on the front, I'd recommend you replace all 4 (and fix what caused the fronts to die first)

The 2IS RWD has staggered and directional tires from the factory- so you can't rotate them from the factory. (at least it did when I purchased- 100% for sure they're still staggered today but it's possible they're not directional which would let you rotate left to right, just not front to back)

extremely informative 
This might be even more off topic, but since we're already talking, if I have a 2010 IS350 (and I think it's RWD) if I get some 19 staggered aftermarket wheels and tires, if I get a flat tire can I just replace it with the factory spare in the trunk and drive until I can get it fixed? Will it drive ok with 3 wheels that are 19", and 1 wheel/tire that is factory? Thank you thank you

Wow, thanks for all the explanation! extremely informative

Now, if it's not similar in overall diameter-
The ISx50 (RWD) doesn't have a mechanical limited slip, so there's somewhat less risk if you have to run different diameter wheel/tire on the same axle for a little while (on an AWD car, or a RWD car with a mechanical limited slip diff, you can physically damage/ruin the system running different sizes for very long)... but I still wouldn't go any further than I had to, and I'd drive pretty slowly as your trac/vsc/vdim systems will likely be confused if the size difference is significant.

There's nothing to do for the "75,000 mile maintenance" except an oil change (and to visually inspection your air and cabin filters- which you can do yourself, free, in about 5 minutes).
Going forward, don't ever, ever, ever, ask a dealer for the "X miles" service- they'll do no extra work and charge you 2-3x as much.
