oligo gene assembly protocol?

[AShaw5]

I am trying to assemble a gene fragment of 200bps by synthesizing it
completely using oligos.  I don't want to make 2 200mer oligos, so I have
made a set of overlapping oligos.  

Does anyone have a protocol for putting these together?  Do I worry about
kinasing them?  Do I heat and renature with all of them mixed together or
one by one?  

Any help with this is appreciated.
