Need some assistance with anacron in Ubuntu

I've got Ubuntu 14.04 I try to learn about using anacron. And there're 3 things so far that I can't understand. Please explain!

1.) WHEN does the anacron command (tast) should be executed for the FIRST TIME?
Let's say today is Wednesday 2 p.m. (14:00) and I've just made a new weekly task for anacron. So when should I be expecting the first execution of it? In other words, what's the starting point here? Weekly, starting from...???

2.) Let's say I've got 3 commands. So this MUST be a script OR... I can stuff all three commands in ONE single anacron task? To be more specific, I want to stop the process, delete the file's content and then to re-start the same stopped process.

3.) Where should I put the commands for anacron? They say that in /etc/anacrontab, but there I see 3 default lines of commands that govern the cron (if I understand that correctly). Should I write my own commands in the same place just below those three?
