Bleed and overlap/ Wire-O question

[vixler]

I'm doing a square book in InDesign that will be printed using Wire-O. The printer said to use 1/8" bleed, so I'm doing that. I also added a half-inch inner margin (keeping important things farther away than that). 

The gutter was auto -et by InDesign. I used squares to create the page colors, of course adding 1/4 bleed on those.

My question is, what do I do with the gutter? Do I push the squares together so that they touch? Or do I leave it empty? What if it was NOT Wire-O, would it make a difference?

What about converting the double spreads to single, non-facing pages?

Your printer will need single pages for their print imposition—the pages need to be rearranged for print.

You could do that but it will be definitely much harder to look at the book without the pages next to each other.
