In pages panel left click on left (or right) page of master spread. Then go to Layout>Margins and Columns and enter values you like. But remember don't select whole spread, just one page.

And about those tutorials, well lynda.com is the best solution in my opinion and Deke McClelland is my favourite.

Maybe it's on locked layer?

I tried many different ways but it won't work, there's no solution to find on google too. It's a pity.

I hope InDesign will be more powerful in the future when it comes to interactive pdf's

When I placed your word file, I got massage about missing fonts (of course I don't have them installed), but cambria math is not even there. In “find font” feature there should be all used fonts listed no matter if they are missing or not. But I don' see cambria math anywhere. I don't know, try copy-paste instead

I'm looking at your image and your text looks good to me, I mean you only got few hyphons. You can play around with hyphenation settings, or you can check optical margin aligment in Story panel so you can push hyphons outside the margin and align text a little bit better.

I don't know if this is the best practice, but I take a text frame and snap it to photo frame and then I double click on black arrow tool (with text frame selected) and then I enter spcific value.

Same problem here!

I know that this has nothing to do with your question but how did you insert image in your post above from hard-drive
