Some modification questions

Hi all,

First of all great theme, but there are some things that I want to change.

1) Body font enlarge with “body {font-size: 15px;}” in quick css increases not everything. For exemple Enfold latest news widget and commentary under Leave a Reply remain small font. How can I change all to size 15?
2) Enfold theme make categories and tags clickable in the text from posts. How can I remove this feature?
3) Bold words are the same color as my links (that I can set in the styling options). How can I make the bold words in the same color as normal text?
4) When I set my blog page by the enfold theme options, he no longer cuts off automatically by 55 words. Can I at this feature back?
5) How can I give the heading tags a different color?
6) The H2 and H3 tags are a little bit to large for my, how can I set a smaller font? (the H1 is smaller than the H2 now, can you see what font the H1 tags are by default?)

Thanks for the time and sorry for my poor english.

Regards,
Miikey
