How to list services/daemons started at boot _and_ check their loading order
Solution 1:
In short:
ls /etc/rc*.d
This shows you what starts at which runlevel, and within each level the order is determined by the number after the letter (K is Kill, S is start).
You can configure what starts at each runlevel with sysv-rc-conf, which is installable with apt.
e.g. on my system apache2 is symlinked in rc5.d as "S20apache2". A link in the same directory with S19 would start before it, something with S21 would start after it.

Solution 2:
Would rcconf and sysv-rc-conf utilities help?
# aptitude install rcconf sysv-rc-conf
Afterwards you can run them by typing rcconf or sysv-rc-conf.
Solution 3:
You can list all services and their status with this simple command:
service --status-all
From the manual:
service --status-all runs all init scripts, in alphabetical order, with the status command. The status is [ + ] for running services, [ - ] for stopped services and [ ? ] for services without a 'status' command. This option only calls status for sysvinit jobs; upstart jobs can be queried in a similar manner with initctl list.
Solution 4:
for i in `find /etc/rc*.d -name S*`; do basename $i | sed -r 's/^S[0-9]+//'; done | sort | uniq
