What kind of help and what model?
That's a pretty good question and usually the type I like to get; however, some of my programsx are acting up. The Via Dolorosa has a tour that is completed in a single day with 14 stations along the way including the two gates you mentioned. Given this information, I would usually use Google Earth (which is free software) to get the distance. Mine, however, is in a folder that will not open right now. If I can get it working in the next few, I will let you know. If not, you can easily do it yourself. It's pretty user-friendly.

Sure. If you were close enough to her to need to ask, I would send something as long as it is not your intention to make her feel bad for not inviting you. Furthermore, it seems as if you have already decided it is the right thing to do, but don't forget to keep your son's feelings in mind.
