Let's start with the assumption that you have done your homework and found the camera that best suits your needs. The first thing that I wound suggest is get a good camera bag, one that will pad and protect your camera. It should also have enough storage so that you can carry extra batteries, etc..
The next accessory that I would suggest is a tripod. You will really need one if you are taking pictures using any level of optical magnification (telephoto lens). Tripods eliminate camera movement, which result from trying to hold the camera perfectly still while shooting. I also recommend using a tripod when shooting in the macro mode. Tripods come in a wide range of sizes, pick the one that will best suit your needs. Camera size is important here, larger cameras need larger tripods. Personally I don't care for monopods, they still allow some movement.
This is the combination that I use for my more serious work:
It is my Panasonic Lumix DMC-FZ30 mounted on a Velbon 9000 tripod. I like this tripod because all the adjustments (vertical, horizontal, and height) can be locked in place. It has a 90 degree rotation of the camera pan that allows changing from the landscape format to the portrait format. It also has a leveling bubble to aid in set up, each leg has two adjusting points to compesate for uneven ground. The camera can be set up anywhere from 22" to 66" off of the ground.
Here is an extreme example of the benefits of using a good tripod:
This is the Pineda Causeway, shot with my FZ30 using 12X (12 power optical magnification) at a range of 5.2 miles, and that point of land visible under the center of the bridge is 9.76 mile away. At that range even the slightest movement would have ruined the picture (blurred), however the image is crisp and clear because I used a steady base with the tripod. BTW, the picture has not been retouched, only resized to fit on the forum.
The rest of you "Shutterbugs" are welcome to jump in and offer your own tips, we can have a lot of fun with our cameras.
