The first thing you need to remember is that when it comes to WILDs and just lucid dreams in general, there really is no "should". In other words, there's no set-in-stone way to do things. It's different for everyone. Contrary to what many people say, swallowing will altimately not effect your WILD. At most, it will make it take slightly longer, because you will realize the presence of your physical body once more, and you'll have to re-find your dream-body--(That's a process that happens on its own. Don't worry about trying to consciously do it.)
As far as HI goes, I tell people to "observe" it, but don't concentrate on it. For me, it works to wait until the "scenery" of things start. They will eventually fade into very short little scenes, that eventually turn into entire dreams. The danger is just falling out of consciousness into non-lucid sleep. Above all else, try to stay passively conscious. But don't over think it
And as far as the "wave" you "should" feel, once again, there is no "should" in WILD. As long as you get to SP, it doesn't matter how you got there.
