The back links to my site all point to my home page. I got many of these back links via reciprocal link exchange that required a link to my home page.
Are these external links having a negative affect of any kind on that page's ranking?
you are giving link to your home page? If so than its a big no no. If you link so many sites on your home page you will loose your authority some helpful sites are fine. Also Google dont like reciprocal linking so beware of that
