Chain for Ultegra 9-speed chainrings and 7-speed cassette

My initial thought is that I'm worrying too much, but here goes:

Getting a new BB and crankset for my old road bike. It is currently 7
speed Ultegra 6400, SIS rear, friction front, non-STI. I am getting
the Ultegra 6500 crank and bottom bracket (on sale, since the 10-speed
6600 stuff is coming out).

I just read the instructions (always a mistake...) that come with the
crank, and it says to use only with compatible chain, CN-HG92 or
CN-7700. Is that really a big deal? I've always used Sedis chains
with good results and was planning on putting one of those on when I
get it all back together.

Is it important to use a 9-speed chain with the new chainrings? If it
is, will that then cause problems with my 7-speed cassettes?

No problem to use a non 9s chain with this crank, we have done this dozens of
times, using a SRAM PC-48(8s chain).
