Hello Huffin_Quakes, welcome to the forums. we will be glad to help you with any questions we can.
you can certainly put newer parts on your frame it is just a matter of getting the correct threading. as for a fixie crank..... we here in C&V are not big on turning bikes into fixies. I am not familiar with a nishiki sport so I am not sure just how nice a bike it is and wether you would be better off selling it and using the money to buy a fixie.
yeah yeah I know you don't get "street cred" for having a store bought bike but a real deal store boiught one will give you less trouble with ill fitting wheels and trying to match brakes and other things.
post a few pics of your bike and let us see what you are starting with.
wheel size.... what size are the tires on your bike? they are likely either 27 x 1 1/4" or 700c x 25 (or someother other number like 23 28) but I betting they are 27" so for replacement wheels you need 27" wheels. however most 'fixie' wheels are 700c and therefore are not a straight replacement for your wheels and you need different brakes.
the cranks are easy but the bearing assembly that attaches them to the bike can be tricky. your bike has a an English threaded bottom bracket (BB) shell. that is the part where the axle or spindle that the cranks attach to. you simply buy a set of cranks and the matching BB for them in English threading.
you do need special tools for this job. one for removing your old cranks, 2 or 3 for removing your old BB and tool for installing the new one.
I hope this helps
