Can anyone point me to some do's and don'ts....??

[Have avoided manual install because Novell docs seem to be written for
LARGE users multi-server / multi-site 1000 users. We have single site with
30 users and will probably opt for TWO server approach GW & rest! ]

where do I start - download ALL the ISO's?

mainly need eDir, GW and iFolder

Do I use OSE as base or SLES ?
