How can I float a specific field to the right of another field
You can just use CSS for this. You will need to find the specific element ID or class for the containing element (div for example) for each of the fields (you can find this out using Firebug with Firefox), then create a CSS rule for each of those elements such as:

#field1 {
  float:left;
  width:150px;
}

#field2 {
  float:left;
  width:150px;
}


You will probably need to then use the CSS rule clear:left; for the field or element that follows after them.
