Your avatar implies you are Marine Corp. If so, thank you sir for your service.
With an 07 your most important item to address right now (immediately, yesterday, etc.) is the ignition switch issue. Your headlight circuit is routed through the ignition switch and the full load is causing far too many ignition switch failures. Triumph has indirectly acknowledged this short-coming with a recall on the latest Roadsters to install a bypass relay.
The solution to your model is to install an H4 Headlight Relay Bypass. You can roll your own or there is an excellent, high quality kit from Eastern Beaver that solves the problem. Many of us, including myself, have installed this kit. Click here =>

Everything else depends on what you have in mind. Perhaps you can elaborate. You'll get a lot of quality responses.
