My plan is to avoid tapping into the 12v and use 5v strips with small phone chargers. Though I might in the one where the radio is since I have 12 volts already there.
How do you plan on powering your 5V phone chargers?  Or do you mean those external battery pack thingies that need recharging from time to time?
If you don't want to run new wires, there are any number of battery powered stick-on LED lamps available from all sorts of places.  For instance, American Science and Surplus sells 
these and 
these others, Ikea has 
these and 
the others, and so on.
