The Draw cap can be lifted in the .exe. Using a hex editor (such as Translhextion), jump to offsets 0x08FE00 and 0x08FE04 (or 589312 and 589316 if you prefer decimal values), and change the value of the first from 09 to 01 and the second from 09 to 64. Now you should always draw 100 units of each spell in battle.
Don't know about modifying fast mode, sorry.
