Could you tell me what is safe to do

SEO is not like adwords where if you make a mistake it is a simple matter of pressing a button to correct the error.

Messing with with so many areas at one time and not really understanding the effects could lead to disatrous consequences. It is better to have a site that is poorly listed on google that you can improve on over many months than have a site that is banned. Take jos advice and take a step back to develop a plan.

SEO takes months of work not days.
