Front/Back Cover in InDesign

[XOatWoodMaxx]

Hi,
We recently changed from Publisher to Indesign CS6. Publisher had a front/back cover template that we used for manuals, but InDesign doesn't seem to have one of these. The printing place that we are using has specific bleed/slug crop requirements, and I am having a bit of trouble seeing how to input these settings to create a proper sized front/back cover. These are the instructions for layout:

For Color & Grayscale Images
Bicubic Downsampling to 300 Pixels /inch for images above 350
Compression Automatic JPEG
Image Quality Maximum
Marks & Bleeds
Crop Marks
Weight 0.25 pt
Offset 0.125 pt
Bleed & Slug
0.125 all around

I thought I pretty much had this understood as editing printing preferences when exporting it as a PDF, but apparently that isn't how it is done either. Can someone give me a good point to start at (like, document size) as far as making a letter size front/back cover, and where to input the above print settings before exporting as a pdf?
