almost live

first off, I want to thank everyone who has been kind enough to offer me help and assistance. I could not have gotten this far without you. =)
I am almost ready… Doing my final rundown before I switch my re-direct and go live with WP from MT. There are still a few problems. One or two plug-ins which are not working for me- but I am more happy with this than not. Design wise, I have two outstanding issues which I cannot figure out for the life of me.

• Why is Tahoma not showing up on my default and on my default-light. I swear on all my boxes, its coming up as aral, no matter what browser I use. This is really annoying me as that I have tried all I can think of to make this not happen.
• <s>Why in my default layout in the “styles” box, does the last selection not formatted like the rest? It’s not like that on the default-light, so why is it on that one??</s> I fixed it by deleting something. I don’t think that was the proper fix but I didn’t need the screenshot anyway do I dumped it.
• I need to open up a browser window at a specfic size- can I use a java snippet here to do that?

The site in question is here: https://www.tekwh0re.net/wp
If I can resolve these issues, I am ready, even though I still feel a little nervous about this.
Thanks!
