I don't think you can just, "end the fed," as much as I would like to see it. The reason is that it's tied into everything else.
Probably the best course to take would be to have congress seize control of the fed, it's technically their job to create the currency anyway, while at the same time allowing for competing currencies, i.e gold, silver.
You just have to be careful not to use a bimetallic currency to avoid dealing with Greshams law.
Read this, it's kinda boring in some spots, but it does give you a pretty damn good education on how money works and it's history in relation to this country.
