ok, this isn't usually my thing, but I tried to help you out. Here goes:
1st picture is page 4 using zoom (you can see how I've zoomed) you can use the arrow buttons to move the page or just touch and move your finger to manipulate the image (cool, I didn't know I could do that!)
2nd picture is page 3 on small (default) font (very difficult to read)
3rd picture is page 3 on medium font (you can see the font in the bottom, loses formatting)
4th picture is page 4 on regular (small) font
5th picture is page 1 on regular (small) font
I played around with changing it to landscape and zooming, and that may be your best bet for these types of pages. Regular font makes it pretty difficult to read, but zoom is very cool. In fact, I have a study guide in pdf that is unreadable on my 505, but it looks like zoom may be my saving grace!
I don't know if this was helpful at all (I used "photo booth" on my mac to take the pics because I'm not tech savvy at all, and that was the only way I could do it easily), but hopefully it was somewhat helpful. I just didn't want you to go a whole day without any response, so I stepped out of my comfort zone
