I am in a time crunch so am asking for as much guidance or samples as possible to accomplish the following in a shell script.

On an Ubuntu Edgy Eft server, do:

1. Stop Apache
2. Stop MySQL
3. tgz all files in webroot and date the archive (e.g. webrootbackup03282007.tgz)
4. tgz all MySQL databases and date the archive (e.g. mysqlbackup03282007.sql..tgz)
5. Start MySQL
6. Start Apache
7. Ship the archives to a Windows Server NTFS share
8. Delete the "local" copies of tgz's.
9. Email me a report

(I will then set cron to run the script as necessary...)

Would be something like:
(
 /etc/init.d/apache stop;
 /etc/init.d/mysql stop;
 DATE=`date "+%Y%m%d"`
 tar -czf /tmp/webrootbackup${DATE}.tgz /your/webroot
 tar -czf /tmp/mysqlbackup${DATE}.tgz /var/lib/mysql
 /etc/init.d/mysql start;
 /etc/init.d/apache start;
 smbmount //windows/share /mnt
 mv /tmp/webrootbackup${DATE}.tgz /tmp/mysqlbackup${DATE}.tgz /mnt
 smbumount /mnt
) | mail -s "backup report" you@example.com

Can't tell you if the pathe to the start-scripts are correct that way, only have a SuSE-box

hrnst42 pretty much nailed it;  however personally whenever stopping and restarting critical services, I'd put in extra checks on those in case an error happens
example, (provided the apache stop exits with an error code if it fails; like it should)
 /etc/init.d/apache stop || mail -s "apache stop error" you@example.com && exit 1

then you know where the script received an error and exits the script so not to potentially cause any problems with future commands.
