Hi, hope i can help,
Remove the battery, you dont need it, only for keeping time when system is off.
You cant boot to vga out of the box, you need a small adapter / you FIRST have to set it in workbench to vga monitor using either a miggy monitor or via tv with a modulator etc??
Games will not show on the vga without a scandoubler/flickerfixer
Not so easy to come by though.
yes you can add cdrom, but i found workbench would not see the cdrom with various cd filesystems. idefix97 demo on aminet sorted that for me. I recommend it.
