I\'m trying to keep the bar_top_container div from wrapping it\'s contents no matter how wide the page is (i.e. both selects should appear always on the same line), this is not

Floating elements wrap as white-space: nowrap does not work for block elements but only for inline elements and text.

You can have both block and inline properties for an element if you display it as ... inline-block!

Here is your code corrected and working:

span.bold are labels
a label is associated to its form element via the for/id attributes
bar_top_block is an id used twice. Should be a class
no need for float: left; as display: inline-block; is used
thus no need for a clearing element either
the .bar_top_block elements are also displayed inline so any whitespace between them is displayed as whitespace. To avoid this, I added a comment that avoid any whitespace though still letting the HTML code readable. The text within is 'no whitespace' so the developer will know that this comment is there for a reason and shouldn't be stripped :)
you can remove the width on body, it's just here for the example
you can play with the overflow property on the container
as IE7 and below don't understand the inline-block value on block elements like div, you must use display: inline and give the element the hasLayout with, for example, zoom: 1;
the best way to target IE7 and below and only those browsers is with a conditional comment
I added support for Fx2 but this is merely for historical reasons :)

    overflow: auto;

.bar_top_block {
    display: -moz-inline-stack; /* Fx2, if you've to support this ooold browser. You should verify that you can still click in the elements, there is a known bug with Fx2 */
    display: inline-block;

I'm suggesting to use a valid form usage:

<form>
  <label>select1: <select><option value="asdf">asdf</option></select></label>
  <label>asdf: <select><option value="blah">-- select action --</option></select></label>
</form>

Hope it helps.
