What mix of development, testing, operations and support is your job?

Mostly development/testing (personally these days I don't think you can be a good developer without being a pretty good tester too). Very little operations/support stuff now - for which I thank my lucky stars :-)

What resources can you recommend, so that I can continue looking for enlightenment?

If you're interested into moving into testing full time I'd give the following a once over:

http://www.testdriven.com

General blog/portal/aggregator site on testing

http://www.testingeducation.org/BBST/

Nice online tutorials/lectures on testing

Lessons Learned in Software Testing: A Context Driven Approach, Cem Kaner, James Bach, Brett Pettichord

Very readable book on software testing in general. A collection of hundreds of good practices and tips.
