The only really confusing/odd thing is the PL+mod system. For whatever reason there are Rare and Legendary classes of mods, and a legendary mod will add +5 to the items PL. So it's worth keeping an eye out for them once you hit level 20 and start getting legendaries.
It's a pretty easy path to 265PL, after that you are basically waiting on weekly reset activities to boost you up to 305PL which is the current max.
Also, in case you have played the first one, your max PL is calculated whenever anything drops, so there is no need to wear your most powerful gear from that PoV
In case you haven't seen, hold onto 5 blue scout rifles for a quest
