How can I stop the 'looping' and am I ready to upload?

I’ve finished my site and I’m happy with how it looks (one main SWF and 5 external swf’s to match the buttons). I’ve tested it and it works like a dream.

First question. When I ‘test movie’, the first external SWF appears but starts looping which I turn off. I then test the buttons and each one works fine. However, will this opening external SWF keep looping once I upload to my website? How can I stop the opening swf from looping?

Second question. Since I am only using Flash for this website, is there anything further that I need to do?

I’m hoping someone can give me some guidance…
