Hello,
1) You can use Inspector of elements (Chrome built in tool) to find out what you should change. Then copy only the necessary part of code!!! and add in custom css to override existing styles http://prntscr.com/bmh6vt
In your case it’s
.onsale { background: #ff0d5f;}
We don’t have New icon.
2) Don’t see the problem with slider arrows. Have you sorted out?
3) How to create such button
http://prntscr.com/bmh9pu you can find here https://www.themepunch.com/revslider-doc/video-layers/
Seems Revolution Slider problem is related to your hosting settings. Contact your hosting provider to solve the problem.
4) Go to Appearance > Widgets > edit useful links html code to change links http://prntscr.com/bmhaz9
Regards
