Amends to WordPress Plugin

Hello, I'm using a WordPress event registration plugin called "Event Expresso". Really happy with it but I need someone to do some CSS amends to make it look more like my site and also address a couple of display issues. The plugin does offer an easy upload of custom CSS. I just don't know much about it so I need some help. Here's what I require: Style Matching: - I need the font size and style changed to match the rest of the site. - I want to orange highlight colour to be changed to blue (the same colour as my site). - Button style should match my site (i.e. same style as 'submit' on my contact page). Things that need to be fixed: - I'd like the box removed from around the 'personal information' section (see attachment for screen grab). - Also when you click 'submit' the 'registration details' section is much taller than is should be and the verification fields don't show any values. I need them to show the values and I need the fields reduced in height (see attachment for screen grab). - Below this the 'additional information' fields are also too tall. I want the height reduced here too. - The events calendar is not appearing as it should. I need this fixed (see attachment for screen grab). Here is a link to the appropriate page of the website.
