Displaying regular price with VAT and adding shipping costs

I just bought your lifetime key. I would like to know how to have the feed display the regular price WITH VAT
and how to add shipping costs based on shipping classes ‘heavy’ and ‘lightweight’. But I don’t know how to. I’m a beginner at this. Can you explain at beginner level? Any type of video would have been great. Thanks in advance.
