Aside from my book:), my favourite is Jack Bogle's Little Book of Common Sense Investing.
If you're going to do research, start with The Little Book of Common Sense Investing. It's the book that got a lot of us started on the journey.
Before you do any investing, I'd suggest you check out the flowchart first: https://i.imgur.com/lSoUQr2.png
You should only start investing in your ROTH once you have a solid emergency fund and no high interest debt. And if you have any student loans, you might want to pay those off first depending on the interest rate.
If you have an efund and no high interest debt, then you can invest - but before you do, I'd recommend reading The Little Book of Common Sense Investing. It's a short read so it shouldn't take you long.
A good start:
John Bogle started Vanguard and championed index funds:
John Bogle of Vanguard has stated that index funds beat managed funds 80% of the time.

>What stocks are doing well?
Don't buy individual stocks. Invest in broad market index funds like VTI and A Random Walk Down Wall Street .
>What do you believe I should do with my access money?
Buy access? Sorry, couldn't help myself. You should keep a base of money in a savings account for an emergency fund. You're going to need a lot of money to start life after college (first and last months' rent, moving expenses, etc.) so think of that as well. Once you've got your cash savings set aside, start funding your retirement. You can contribute up to $5500 per year to an IRA. Start now and that money will have 46 years to grow.
