Please god tell me this is all I need for manual-swap pedals.

I would definitely use extensions and universal joints to get to some of those nuts. Since there won't be any corrosion these should be relatively easy nuts to remove. It requires a little bit of wiggling but eventually it will come out.

Remember that this will also release your brake booster. So open up the hood and you can pull the booster from outside to get the studs loose.
