Thanks.
So what is the major difference between something like the FL-36 and
the Sunpak 383 (beyond price).
The FL-36 is fully automatic in that in general you just have to put the flash on the camera and shoot. Thie is called TTL mode (through the lens, where the camera and flash work together to determine the exposure). Another thing the TTL flashes do is provide a red light for the camera to focus by, instead of using the flash pulses with the pop-up flash.
ith the generic flashes like the Sunpak 383, you have to set the camera in manual mode, set the flash in 'auto' mode, set both to the same ISO, and set the aperture to agree with the setting on the flash, set the shutter speed to determine how much ambenient light you want to capture. It isn't that hard, and usually you can set a My Mode to remember the settings when using the the flash. It just takes a little bit of learning. I must admit, my keeper ratio did go up when I went from an auto flash to a TTL flash.
Also the only lense I have is the 14 - 45 mm. Is their another lense
I should get?
I will be mostly using the camera for pictures of my kids and family.
If so what brand/type and where could I get it for a decent price?
For normal family portraits, this is fine. If you want to photograph things at a distance you could go for a zoom lens like the 40-150mm. Note with the E-500, you will have to watch your shutter speed with a zoom lens to avoid camera shake unless you are shooting in bright sunlight. Again, it isn't rocket science, but you do have to watch what the settings are in the camera. There are lenses at higher cost that give you things like more zoom, a wider angle, shoot closeup (macro), or the ability to shoot in lower light without a flash.
