I want to buy the best crankset and bottom brackets for xc-racer... have to be light and very strong... Any sugestion???

FSA Carbon pro with a FSA Extreme Pro ti BB !

that's my setup...right now...am planning on some lighter rings and bolts though

tune bigfoot & rf taperlock ti; ta-specialité rings and al-bolts

Try Fly Sports Propeller crankset! Weight with bottom bracket is only 390 grams! Not only is it light but its one of the best looking cranks on the market. http://www.fly-sports.com/products/cranks.html

Ehm...are you serious?
I recommend you to read this thread:

If you want Light AND strong AND stiff, take a look at the XTR 2003 Crankset !!!
If you want to save extra weight, you will have to make compromise on the Strength and Stiffness !

My bike weight 8,9 kg with this crankset and with a 21" M5 frame so it's the proof that this crankset is not too heavy for a very light XC bike !

I have not used the ISIS BB yet, but from what I read, they have their share of problems with bearing reliability. Square taper BBs are generally lighter than ISIS and to tell you the truth I don't think I can feel any flex in my square taper. The Race Face Carbon Next LP crankset is on sale at several web retailers for $189 US with rings. For my money, Id go with a RF Next with the Phil Wood Ti BB and swap the RF rings for Sugino with AL chainring and crank bolts. You will end up with a very light, stiff and inexpensive setup.

Admin posted a dead link discussing something about the propeller cranks...I want a set too, but is there a problem with them since the link is dead?
