What is or can you direct me to any info on deductibility of educational and industry related materials, along the lines of say Union, or for example as a broker I used to be able to deduct "continuing educational" expenses, as well as most all publications involving my "profession"?

The IRS website has a wealth of information. The deductions you ask about are miscellaneous itemized deductions.
The IRS has a page devoted to these deductions, with links to other related topics.
As to whether or not you should (or need to) make an estimated payment, you should discuss this with your own professional tax adviser. He or she can run the numbers and see what's right for your situation.
