So far I have been looking at Temron 18-250 and Pentax 50 mm. The reviews have been great for these 2 lens, but are they good enough for good wedding photography?
Regs,

PS. I also want to add that most Indian weddings take place in night and, ppl wear bright colors.
I'm not an expert, but...
At night I think you would struggle with the relatively small maximum aperture of something like the Tamron. Don't forget that SR increases your ability to hand hold at slow speeds, but it doesn't make your subjects move any slower.
Also, although the 18-250 is generally well regarded (for a super zoom) its rendering pales in comparison with a nice prime or a shorter, more highly optimised zoom. In high pressure photography you really want a lens that doesn't come with too many compromises, making a consumer super zoom a less than ideal choice. The obvious choice in the Pentax system for a standard zoom would be the 16-50/2.8 and you'd probably want a longer zoom as well.
The 50mm (I'm guessing you mean the FA 50/1.4?) is a much-loved lens and would certainly come in handy, especially for shots of one or two people.
How many bodies are you buying? As a professional wedding photographer you'd want two as an absolute minimum (probably three or more as bodies will probably need servicing in time and you always need to have at least two for the wedding itself). Equipment failure will not fly as an excuse if you miss critical shots - it's your responsibility to make sure you have sufficient equipment to avoid screw-ups.
There are other smaller items to consider. You may well want a good flash (Pentax AF540FGZ, Metz 48 or 58 AF-1 etc.) and you'll need piles of batteries and memory cards to keep everything up and running. No doubt others will have more suggestions.
