Sure can, but lots of folks forget to swith to HTML mode first or the WYSIWYG editor messes up the code after the fact, etc. Postcasa allows for adding the shortcode directly to the WYSIWYG editor with no problems. Its a simple plugin designed for easy access, nothing more.
Yes, to a degree. The [postcasa] tag options govern the actual flash slideshow, but you can style the surrounding HTML paragraph tags by using the included 'postcasa' class.

p.postcasa {
margin: 10px;
padding: 10px;
border: 1px #000000 solid;
}
