Have fun with the pin! I remember I got my first pin just over a year ago and fished it both summer and winter (ice fishing lakers + pin = awesome sauce). Just use it for everything, bottom bouncing, casting spinners and cranks, multi-species (carp + pin = awesome sauce as well). Use it all the time, and you will learn how to cast in several ways and how to handle and fight fish.
As for hi-vis line, I found that I only used it the first fall, after I got used to using it, I ditched it for some regular mono. Like everyone says, Raven is decent line, cheap and handles nicely. I first thought it was 'cheap' line because of the price, but I still line up with it every once and a while. Hi-Vis line ain't needed once you grasp the ebb and flow of pinning. So if you eventually use regular line for your main line then you won't need a shot line. That's too much line to be carrying around in the wader pockets anyways lol.
I don't use special leader line either, just straight up mono. Don't have issues getting hook ups, as long as the roe is deliciously juicy! I guess some spots the fish are a lot more spooky and people will downsize to 4lb and under. But if the fishing is that tough, I'd change spots, change rivers, or pack it in anyways. I once did get the special flouro leader but didn't find any difference in hookup %
