Iv got 2x 8gb memory cards! Would that be enough' going for just short of 4 weeks!
It depends. Are you shooting RAW or Jpeg? If it was me going on a once in a lifetime trip, I would definitely shoot RAW or maybe RAW+Jpeg.
Also depends on whether you'll be taking a laptop to copy the photos onto.
If you're taking an iPad, get the camera connection kit to download photos to the iPad.
My camera is 14.2Mpixels like the Nikon D3100, so a RAW photo file is about 14MB and a jpeg comes out at about 4-5MB.
So one 8GB card will store around 550 RAW files or 1600 jpegs.
If you shoot RAW + Jpeg that would only give you around 420 images on an 8GB card.
If you shot in RAW and got 550 files on a card, with 2 cards that's 1100, that would only give you about 40 shots per day of your 4 week trip.
Is that enough?
Also I need to get a remote for long exposures' and a uv lense cover recommended due to the sun?
You don't *need* a remote for long exposures, you can just use the self-timer mode (set it to 2sec delay) so that you don't wobble the camera (which will be on a tripod) when you press the shutter button. A remote is handy, as you don't have to wait around so much.
A UV filter doesn't cut down the light, they are needed when shooting film, but not needed for digital. A lot of people use them, but their only purpose is to protect the camera's lens. Personally, although I've got them, I've kinda gone off using them in everyday stuff.
See this for the UV filter arguments:
http://www.digitalrev.com/article/uv-filter-vs-no-uv/OTMwNA_A_AWhat you want for bright shots, is either ND (neutral density) filters, which cut down the amount of light going through the lens (allowing wider apertures or slower shutter speeds) or a Polariser (aka: CPL) which cuts down the light, cuts down reflections and will stop the sky being a white out on a bright day, making it a nicer blue.
