Hey Janet -- lots of great stuff on this site in particular... definitely a great place to keep bookmarked!
Some other thoughts:
* Start picking up the lingo. If you see a term / concept, spend some time researching it from several sources. Internet research is quick and will get you lots of angles -- don't limit yourself to just one site/source.
* Are you looking to go into (IT) systems analysis? Look into different types of development methodologies: Waterfall methodologies versus Iterative methodologies (e.g. Unified Process, Agile, Scrum, etc.)
* Are you looking to focus on the process side? Look into formalized ways of process modeling, e.g. BPMN
* I love books... Amazon.com is my friend. If your budget allows for it, grab some books on these topics. I find that used books are a great bargain -- I may not get through every single page of every book I get, but I have a reference for future use if I want to do a deep dive at a later time.
* Check out an industry association like IIBA: the International Institute of Business Analysis. If there's a local chapter organized near you (geographically), look to go there in-person. Ask for a such guidance there, and you may potentially find a mentor in the field.
From a career perspective, I'd manage expectations by saying you're likely to do a lot of documentation in early BA roles (your mileage may vary based on the type of BA role you're targeting). Get to know and love the concept of requirements: stakeholder requirements, product requirements. Many different terms/categories, but likely all will come up. Keep an eye open for how requirements are defined, and also how to (effectively) document and share them.
Hoping some others can chime in!
