Financial Planning: Best information sources and research tools?

I am new in financial planning and am approaching the profession with several years experience working in personal trusts and have just completed a financial planning course. I am considering going out on my own and am trying to get some tips and ideas as to the best ways to stay informed and to provide clients with the best expertise and skill set possible.

Does anyone have preferences and/or advice as to the best ways to stay current and in compliance with legal, tax and market changes?

What are some useful tools and/or sources for research on on complex or unique asset and planning situations?

Any ideas or thoughts would be appreciated.
