Don't book any tickets (well unless you can cancel without penalty) until your visa has been approved.
In connection with an itinerary, you'll need to provide some detail on your accommodation arrangements and any travel plans during the duration of your visit.
Most important will be showing that reasons to return home outweigh reasons to stay here.
Good Luck.
Noted Terpe. Thank you.
