Firebug can't find these ??? HELP - STUMPED

Alright, I've been spending about 11 hours with this and I'm ready to give up (but can't) ... looking for some help from the pros ...
Of course I've been using firebug, didn't do me much good for this though.

I simply cannot find the elements/margins which are located directly below the main menu with all of its tabs and directly above the flash promo!
I'm talking about that 19px tall element which contains Hello Guest, Join, Login, in tiny letters to the right.

Yes, I actually found it and also the 3 images that control the look and feel of that section, but no matter what I do with those 3 images, to include creating them from scratch and saving them as png, jpg, or gif (also making appropriate changes in the top_menu.css file) ... Dolphin simply ignores these images. I've been working with images for 15 years so that's not the problem ....
Yes, I have the cache for D7 disabled.

Then there's the horizontal margin right above and below this element ... it's a thin margin about 8 or 10 px tall.
I simply cannot find the element(s) which control that margin so that I can change the color to something else.
Right now those two (upper & lower) margins are transparent because I'm using an image for my page background. When I found the right file to fill in the margins between all of the page blocks, for some reason those three areas were not filled in and those are the three that I've been trying to locate endlessly.

The third horizontal margin that I can't find is the one that's located directly between the footer block with the copyright and the bottom of the page with the main blocks and columns. Using FF 3.5 I'm seeing a margin that's apx. 5 px. tall and would like for this to disappear.
Using Linux, I can only test with IE6 (which of course doesn't work anymore), Firefox, and a couple of other browsers. I have no idea what the page looks like with IE7 or IE8 which is of course also very important.

PLEASE ... HELP ... SOMEBODY .... (see link to the left of this text)

It would help to know if your running a custom template or your simply changing the existing UNI template. Where images need to be stored is dependent on the template.

The margin above the breadcrumb is in general.css

Thanks deano92964,

I'm not using any other templates ... just modifying what's already there.
However, all of the changes that I made took place in the base template, including all image adjustments.
As you can see by the site, it's still work in progress but those horizontal margins joined together make up a large piece of the overall appearance. I'll come back and let you know what I was able to find.

Okay, I already had most of that set correctly, but I didn't have the background added under div.sys_breadcrumb { which made all the difference in the world. Raised the height of that to 35 after removing the margins and adding the background, which then merged everything together nicely.

Still have the problem with that footer margin which seems to elude me, any thoughts on that? Thanks again.

Same location as the upper margin.

general.css

}

Change the 5px to 0px

Thanks, that did it.

Working with half a dozen files, numerous images and other things at the same time just makes your eyeballs bleed after awhile. I was looking everywhere but there (Footer, Copyright, Index, etc.)
