Lum: Yes I did solder the illumination LEDs right to the pads where the bulb (base) contacts touch. In some cases I needed to use several White LEDs to get the illumination to spread evenly.
Over the last few years - seems like they've made good technology progress with not only brighter LEDs but ones that illuminate over a wider spread. Some folks have just taken very bright LEDs and filed the top domes flat causing the light to disperse that way.
If I were to do this job again today -- I'd either re-base the bulbs with LEDs (just to make the retrofit easier) or only solder a single LEDs onto the boards using brighter units designed to disperse the light better.
At the time -- found the 5mm white LEDs on eBay (came from Japan). But they were a little harder to get back then (the really bright ones). Here's an example of what's out there today (a few years back 8-10k mcd were the brightest) - these seem almost dangerous (from a direct eye issue):

I used just 1 resistor for all the illumination LEDs - found the common power feed point on the pods circuit boards, cut the trace and bridged it with a 1/4w 1000 ohm resistor. White LEDs don't require all the much current for good illumiation - 2mA each or so. On the climiate pod (if I'm remembering correctly?) - had to install the resistor on the cable that runs from the daughterboard to the main climate board - was the only place to insert it w/out too much of a hassle. Daughterboard is where the rear pod wiring harness connectors are soldered...
