Typography -- Main Article

I'm now slowly approaching the time when I'll have to transfer my article from a Microsoft Word document to Adobe Photoshop where I have created the double page spreads for my main article. As you can see below I've already blocked-in my columns that I'm going to put my article in however my main concern now is the typeface of my article.

I've already selected the font for the title of my article but I now have to select the font for the lead and main body of the article (I'd also like to change the font that I've used for the section folio). With regards to the main body, the text is going to be 10pt or 11pt (depending on the typeface) and I know that I'm going to have to consider the x-height of the text to ensure that the article is comfortable to read (I'll be able to judge whether I've got it right the next time I print my pages).
