I probably beat to a different drummer than most around here. But I highly recommend joining a investing club through NAIC. After having a money manager lose a bunch of my money, I joined a club with the sole goal of "losing my money at a slower rate than the professionals."
It was great to not only learn financials, but also be in a group with people from wildly different backgrounds, ages, etc. Since no one was drinking the same Kool-Aid, it helped make sure you weren't seeing investments with those rose colored glasses on. If you thought something was a great investment, you had to show the group the numbers/the reasons.
After gaining confidence, I started investing on my own and never looked back.
The club I joined had something like a $50 a month contribution, so you can join one now and learn for relatively little money and risk while you are building your emergency fund. Usually you have to take a couple of classes and attend a few meeting before you can join.
I'm less concerned about Roth/401K/etc as the dear government can change tax laws at anytime. Mostly I'd work on building up the funds and not stress over the type of account.
