hyperref Warning: Draft mode on

According to the documentation,

\hypersetup{final}

should do the trick.

Try:

\usepackage[draft=false]{hyperref}

Additionally, if you want to leave hyperref on for links but keep the same printed output, use something like:

\usepackage[hidelinks,draft=false]{hyperref}

When combined with a package like

\usepackage[obeyDraft]{todonotes}

it's really great and you can just change the draft option in the \documentclass[] and you can turn your 'to do' notes on and off really easily.
