Treat it as a new PC. Unplug the other drives, and use an install CD to
handle formatting and everything else (including base installation of
the OS). Set up the drive however you want wrt partitions.
'dd' will at best get you a 500GB disk on your new 900G SSD. and then
you'll have to fight with it (fdisk, etc.) in order to use the rest of
the space.
NB - you don't /have/ to mess with unplugging the drives, but I like
/dev/sda being my main drive, which probably wouldn't happen if you left
the other drives plugged in. It's more of a "do things the way I want"
thing than anything else
Once the base system is installed (including any programs you use), plug
the other drives back in, and copy important stuff (e.g. your $HOME,
/etc, and anything else) from the 500G spinning rust drive to your main
SSD.

Never not backup. Other than that, I don't think there's much in the
way of "stuff to watch out for".
