retrofit 2003 campy centaur triple group

Hi,
would like know if is it compatible to retrofit this group
=Front Derailleur is 28.6 mm diameter, down swing, down pull.
Rear Derailleur is a long cage 9 speed "Racing T".
BB is 68 mm.=
onto an older atala late 80's early 90's?, can i use the friction
shifters on the bike or do i have to get specific indexed shifters &
is there a bar end shifter option?
thanks for any help and info I'm a little worried about the difference
in age of the two and how it will affect the installation and
functionality
