I would suggest that you post your questions, rather than simply asking if there are experts out here. Many of us do not consider ourselves experts, but probably have experienced some of the same issues you have questions about. I for one think I am very good at paying way too much in taxes.
Also, if you ask specific questions, the answers can be reviewed by others and you can be saved from bad advice that way.
So, go for it. There are no dumb questions about taxes. Just dumb tax laws and rules to wade through.
