Walk 'n' Click: Camera accessories

In my perspective, investing on the below is really a good thought to protect your camera and to get better quality images.

Must have -

LCD Screen protector - Get a hard LCD scratch protector screen guard for your LCD display, to avoid dust, scratch, and finger print marks.
Lens Cap/rear cap - Always have the lens cap on the lens to avoid dust and damage to lens. And also the rear cap when you remove them camera.
Lens Hood - To protect the lens when in crowd, or trekking by not damaging on the sides. Avoids lens flares while shooting images.
Lens filters - To start with owning a UV and Polariser filter is good.... Check more on Types of Lens Filter (http://georgeography.blogspot.in/2012/07/types-of-lens-filter.html)
Tripods/Monopods - To get steady image in low light conditions and for long exposure shots.
Neck/hand Straps - To get a grip and you do not leave the camera down when there is push or pull.
Silica Gels - To remove moisture and thus avoid fungus formation in lens or camera.
Chamois - Its made up of leather. To clean LCD and lens or use soft cleaning cloth, along with a Cleaning Kit.
Additional Battery and Memory cards (Class 4, 6 or 10 SD cards) to shoot more photos.
Camera Bags - To store your gear & all of the above accessories and protect from all weather condition, preferably a backpack which less strain-full while carrying around. (I also prefer to carry laptop along with these, so chose one which also as Laptop compartment. Choices differ here.)
