You will know if they are vanity mirror lights as they will be about 31mm long and very thin, with metal bits on both ends. Be careful when trying to fit them though, the light covers pop off ok (work from the outside edge inwards), but you need to push 2 bits of lower trim inwards so it slots back in when refitting.
The interior lights in a roadster pop out easily - the plastic cover (that you push to turn on/off) pops off if you use a trim removal tool, pry it under the outside edge and push. Incidentally, a set of trim removal tools are cheap on ebay and will save you a lot of hassle.
The boot is hard, but if you can get your head inside, look up at the dome covering the bulb and you should see a bit of plastic holding it in place. It is hinged on the side closest to the front of the car (IIRC) so press the side closest to the rear. Also to note, this was the only bulb that caused me hassle, I blew a fuse when installing a new LED one, they run off a red 10a fuse in the drivers kickpanel if you run into trouble.
