Is this a good tool to drill holes in masonry ceiling to hang a lamp? My hammer drill with masonry bit is not doing the job.

Yes.. they take their own bits, but it does a great job drilling holes. I've drilled 1/2" holes through my solid 8" thick foundation several times. It is hard concrete with river rock from the 1940's so it is very hard. It goes through pretty quick.

where are SDS & SDS Plus drill bits sold. Is there a set. How much

You can find them list on Amazon. Here is a link for the SDS Plus bit:http://www.amazon.com/s/ref=nb_sb_ss_i_1_4?url=search-alias%3Daps&field-keywords=sds%20drill%20bits&sprefix=sds+%2Caps%2C214

What is the Warranty? I read the motor burned out on a new one and they not replace it.
