Don't fret the "letting juice sit" stuff just yet. You have to get close to the target before you can sight the rifle.
Nic absorbs differently in every person and you have to find your level. It does not have as much to do with your smoking as we'd hope.
Different flavors in small bottles so you are not stuck with a big bottle of "tastes like the liner of a diaper pail" juice. What may be great to me may taste like car tire to you and visa versa. I had a devil of a time finding a flavor that would allow me to never consider picking up another cig until I went completely away from the flavor path I was following. Once I found that flavor, never picking up another cig was as easy as walking. My son, sister, cousin, and a number of friends all had the same experience. They tried a flavor that they were sure they would hate, and loved it, and didn't want to smoke anymore. (That is why I suggest trying different flavors.)
VG blend, I will assume is a fixed percentage of VG in the mix. A custom blend would be where you choose the PG/VG ratio.
Generally: VG=more vapor & less throat hit and PG=more TH & stronger flavor (Not exactly true, but close enough for someone starting out.) So folks adjust the PG/VG ratio to dial in that perfect vape. I'd suggest going simple at the start and dial in as you gain experience.
