iPhone photo app - fixed order?

hey all,

I have my photos organised into events in iPhoto, arranged by title; when synced to the phone however, they appear arranged by date from newest to oldest. Is there any way to change this ordering system?

Also, does anyone know why iPhoto says my library is 1.5 GB in size, but it takes up 3.8 GB of space on the phone?

I really want to make use of the fact that I can carry all my photos with me but these roadblocks are frustrating ...

 

I understand people might not be sure of the problem but if anyone can suggest anything that I could try, it'd really help me out ...
