I've done a search and found some great info on income tax but I have a couple of questions still to be answered.........

1- Is there any way my step daughter can be counted as a child a I support (which I do!) in the eyes of the Thai tax man?

2 - I heard about tax deductions if you take out health / life insurance / pensions - any info on this?

TIA

If you are legally married to your wife, and you are filing a joint return, and you meet all the other restrictions for claiming a dependent, then there should be no issues claiming her. If your wife files a separate return, then your wife may claim the deduction.

As for other deductions, they are all listed here:
