I would say that you should be able to trust your shop. Especially if you told them your concerns and what target you want. It's quite an overhaul with all the replacement parts you mentioned. The feeling will change and they should get the best alignment out of your setup. Even with mods or the m030.
Where did you drop the car?

Rs+10 and the rest as RS spec is fine. You won't have travel issues.

What you might find, relative to your tires, temperatures, road types etc, that on the street, on street tires, that you don't have enough grip to warrant the RS alignment, and you may find you have too much negative camber, particularly in the front.

For street use, i keep camber down to a small roar, -0.5 degrees front. -1 or just under that in the rear. Reason being, relative to my setup, this is well balanced for me in terms of understeer. I have big sway bars and on coos street tires, the car barely leans, so my setup is where i find max grip. I prefer the stock rs toe settings for street...but truely if i wanted to "drive" all the time, i actually prefer a little tow out. But i don't pay attention anymore enough to warrant those things...so i like it a little easier. My car is very well behaved.

Bottom line...yea you can do rs specs. But if you find the front camber a little pitchy or tram-line-ish...dial that back. You'll have to drive the car hard to really get a sense for what gives better grip. Dead stock alignment is fine for all-around, but i find i need to either add grip to the front or take away from the rear, in general, to get the car balanced out. And the stock alignment and car setup leaves me with way too much understeer. On both c2 and c4
