Interior Light Replacement... Damage

[lkv0315]

So for Christmas my family gave me some CREE LED interior lights that replace the factory bulbs. All was going well until I got to the Front Map/Dome light, when I encountered the following issues.

1) The Light unit was an absolute pain to remove which I was afraid would cause me to end up damaging it. Turns out I definitely did damage it, as it no longer sits snugly up inside the main plastic bracket and just kind of hangs there.

Which leads me to my next question, is the dome light a multi-piece unit or would I have to order the whole new thing, because I think I may have just broken off little plastic brackets that hold it up in place.

2) There are three light-bulbs, the Left and Right ones came out of the unit and the replacements went back in just fine. The center one does not fit, and I believe it is a design issue by the company that made them.
So would it be an okay idea to try and widen the hole a bit or do I run the risk of screwing the reflective material on the inside of the unit up?

Finally, I know that there is a separate forum section for this but does anyone know where I can source the following things (even if this means it may be from you, I will still take an offer)

1) (if necessary based on above info) A new Dome/Map Light or whatever piece of the light I may have damaged.

2)Foot well light lens/holder (as I was removing it, the main bracket piece broke and it will no longer stay up inside the panel.

3) A more reliable place to purchase a set of lights from as I specifically noted in my order to the Chinese eBay company that I had the model with the sunroof and I did not have a rear dome light, but they sent the rear dome light bulbs anyway but no bulbs for the rear reading lights.
