Where can I change the font settings for comments section. I checked the administrator control panel but there is no option for that. I would like to be able to change the font type and font size for the comments.

This should probably be done by editing the template css file. Some of the items you will want to edit are:
#comments
.comment-body
#comment-head
#wholecomment
#comment-wrap

Solved... if using eliteadvanced template, the changes can be made in the elite.css file starting line 83: blockquote {.....}
