FYI - I just moved your post from the general forum to a more specific one so you can get more specialized help and advice.
Congratulations on getting your first bike! Sorry to hear it's a work in progress one but anything is better than nothing.
About the modifications... I'd first see if you like that bike first rather than see you spend quite a bit of money on new plastics for it and later find out it's not what you really want. A FZR600R (or any sportbike) is purpose built and if you are not riding it for that purpose you'll soon find it has limitations.
For plastics, if you go new, look to spend over a $1000+ on them. Fairings (as they are called) are NOT CHEAP, that's one of the downsides to owning a sportbike. About adding more lights, well, you really can't (on a Cruiser you can). But you can replace the H4 bulb (or what is in there) with a brighter version (not increased wattage one!), like the Sylvania Silverstar or such.
Fitting a different fairing from another manufacturer can be done, but it's all custom work, expect to easily exceed the cost of this older bike to do this. Again, see if you like it first. As with any new rider, you have a good chance of dropping it once (most likely in your garage or driveway) so wait a bit and scuff up those old fairing before getting new custom ones.
