If you are talking StarSan then right over the foam is fine. At that amount the stuff has pretty much zero impact on anything. Besides letting you know it is doing its job of course.
Sure, just use caffinated soda syrup and water directly in the keg. Remember, that these kegs were originally used for Coke & Pepsi, and sometimes when you get a keg you can still smell it, or see the last dregs of what was once pepsi. Then there's the guy somewhere who got his keg with ancient pepsi still in it.
The only "issue" with having soda directly in the keg is that some sodas will really leave it's odor in those o-rings and possibly the tubing, so it will probably be a dedicated line for a single type of soda. Try switching from rootbeer to sprite or orange soda (I know, I know, none are caf, but it's a flavor example) and it may not work well. There's some things about some lines not holding the odor/flavor, and barrier devices too.
Do you mean the 1-oz meter pour spouts to go on top of liquor bottles? Or something else?
