At the very left column should only be a single bracket, being a closing curly bracket. You have multiple brackets here, meaning you've closed the dataTags too early and attempted to open a second set, which is where your error comes from; all dataTags can only be in the same set.
You are also missing a comma after your first Equipment. To add a color to leather armor, you would apply the "display" tag within the "tag" tag, and then insert the "color" tag into the "display" tag. You need to use a decimal number as the value, which you can pick from here: http://www.mathsisfun.com/hexadecimal-decimal-colors.html
For your equipment, you've inserted 6 values when you can only use 5. The order is: Hands, Feet, Legs, Chest, Head. You've inserted a bow after the Head slot, which is not applicable, thus I've removed it.
1.8 no longer supports numerical IDs for items, so you will have to switch to the new format.
