Most of the time you don't need to meter every shot. (there is another lengthy thread about this...). Then as Sparky says, leave the darkslide in your pocket. Actually I'm more inclined to leave the darkslide home and the lenscap in my pocket, but either method works.
After a bit of practice you'll get the hang of it... or perhaps not, and there will be another bargain Hassy in the classifieds
My first Hasselblad, which I bought and later traded off several years ago had a prism finder. The one I recently aquired only has the waist level. For me they are easier to work with with a prism. If your's doesn't have one, then you may want to consider it for your next major addition. I was looking around for one last night, and they are not even very dear if you don't want to be too picky about looks.
