iWork-Missing fonts after Leopard install

I installed Leopard today and everything went just fine. The only problem that I have is when I open any template, I am given the notice that helvetica-narrow is substituted for the missing font helvetica. The warning was never given before moving to Leopard, so I assume the font was there with Tiger. I have gone to the Leopard install disk to find the font, but the only choice I can find is to install a bunch of foreign language fonts. Can anyone tell me where to get the apparently missing font, and how to install it?
Also, when I make a template for Numbers, it always makes 4 pages at a time. When I go to print, I have to specify to print the current page, or it will print the current one, as well as 3 blank ones. Is there any way of making a template consisting of only one sheet?

Thanks in advance for any replies.

I should add that I was very apprehensive about installing Leopard, as there have been so many posts indicating massive problems. I did the basic quick install, and it couldn't have been easier.

Just installed Leopard and missing Helvetica too

Both in iWeb and Pages - the error is reported re missing Helvetica and yet when I look at fonts library Helvetica Regular is listed... What do you do to sort it out?
