Comment customization help: remove/change form border [Solved], drop-down box borders

[weehobbit]

I've been messing around with the comment customizations and I believe my problems are easy fixes but I haven't found a post that gives all the details of attributes that can be changed with comments. The starter style-sheet is helpful but I think there's more attributes that I'm unaware of. Is there some sort of comprehensive list of all variables that can be changed that I'm missing?

-Browser: Firefox
-Account: Paid (but fixes should be CSS only)

Want to fix:

1. Remove/Change the black border on the comment form (is that what it's called? I've kind of been just messing around so I don't know the proper names for all the attributes). To clarify: I get the black border when hitting 'leave a comment' from the 'entry' view. The border doesn't show up if I hit comment from the 'recent entries' view.
   Solved! Thanks to av8rmike in comments.
   
   
2. Have a border on the drop-down menu for userpics, but not a border for each item on the drop-down menu (right now in my CSS when i specify a border it effects both parts.)

Screenshot of what I want to change:


My CSS relevant to comment page customizations:
#comments {padding: 0px; border:0px;}

#comments input, #comments textarea {
font-family: calibri, \"trebuchet ms\", tahoma, verdana, arial, sans-serif;
background-color: #bee783;
border: 0px;
}

#comments button, #comments select, #comments submit, #comments option {
font-family: calibri, \"trebuchet ms\", tahoma, verdana, arial, sans-serif;
background-color: #ffffff;
border: 1px solid #bee783;
}

#comment-form textarea {
font-family: calibri, \"trebuchet ms\", tahoma, verdana, arial, sans-serif;
background-color: #bee783;
border: 0px;
}

#comment-form {
border:0px;
}

Thank you for any help! :)
