Looking for advise

When I get paid for shooting I get trigger happy using my latest and greatest Nikon or Sony and spend boooring hours in front of the computer postprocessing.
I bet you do. I've never had the luxury of being paid for photography, so getting 'the shot' isn't time-limited. If I was shooting an event or something, I'd be more inclined to go for broke and hope that I've more suitable shots than I intended to get.
Photography forms part of my job to initially record and provide a permanent record of what I see, dependant up on the job type, for use at a later time and to photographically record certain things while working through a job. I could easily get trigger happy with the shutter as I don't do the post processing but still have to input metadata for certain images and types which isn't the easiest or most pleasant activity on a 10" laptop screen. Hence my Hasselblad type approach, it saves me time in the long run.
As others have said, Talk Photography is good source of info but as/when you get the camera, take the kit out and use it to get used it to it. Find yourself a scene to photograph and take the same image at differing focal lengths and apertures but keep the ISO constant i.e. 400 ISO - 18mm f2.8, 18mm f8, 18mm f16 and the repeat at 35mm and 55mm - I'd do the same for 70 - 300 as well and compare the pictures on the pc.

If you need software, download/install FastStone Image Viewer, it'll let you view and do some basic editing to the images if you want.

As a general rule of thumb, especially if you're hand holding the camera, keep your shutter speed above your focal length, so if you're shooting at 55mm above 1/60th, 200mm above 1/200th.

Itmay well be @Nisse - but that's what the OP's gottenfor himself and there's many a good tune played on a old fiddle... If people can help him get the best outof it and he manages to get some decent imagesfrom the trip, it's a job well done.
Thanks buddy my view totally.
I like, previously loved items, it could be my extensive work tools, or new hobbies.
And if we dont take to it then, not much lost and maybe a little gained.
