in terms of textarea here is an example from one of my theme's style sheet:
textarea {
width: 400px; /* set to preferred width */
color: #000;
background: #efefef;
border: 1px solid #000;
font-family: Verdana, Arial, helvetica, sans-serif;
font-size: 10px;
font-weight: normal
}
this works well for me, besides editing core files is no fun.
in terms of timezone you will need to edit (shorten) text in:
language/yourlanguage/timezone.php
