Flash Newbie

While I have quite a bit of experience with natural light, and can get by with studio flash, I fancy trying my hand with outdoor fill-in flash as I have seen some great images with it and I know there are quite a few experts on this subject on this forum.

Kit: I have a Samsung SEF-36PZF which I picked up cheap when they were discontinued, which I believe is a clone of the well respected Pentax AF 360FGZ. I also have a very old Metx 45 CT-3 which someone gave me (as well as the wotsit to reduce the trigger voltage to connecct it to the hotshoe). I also have a brolly.

A few questions:
1.) Is this kit sufficient, or do I need to buy something else? If so what?
2.) What is the best way to trigger the SEF-36PZF remotely, and which mode should I use?
3.) What is the best tutorial on pairing the body with the SEF-36PZF, as I tend to forget after trying it each time.

All help most appreciated.
