Well with the setup that you have now there really is no need to upgrade to the bigger injectors unless you have something like a MAP adjuster to dial them in because they will more than likely run too rich. For the budget you mentioned I would recomend going up to a 100 shot of the nitrous, which your engine can handle no problem. With what you have left over get a performance cam and lifter set. I am not as familiar with the 4.7 as I am the 4.0 but I don't think there are any headers that will fit as a direct bolt-on replacement without doing some fabrication. You won't get a huge increase from headers and a high-flow cat but it's not a bad idea to upgrade the entire exhaust so if you do get some headers and a new cat then I would recomend upgrading the front/head pipe as well so there aren't any bottle necks. But, for the money, the larger N2O shot and the cam will get you the largest drop in your E.T. If you do the nitrous I would recomend a fuel pressure cut off switch, and in the future get a bottle heater or pressure controller (heats and/or cools), and a purge valve. You may also want to get some gauges to let you know what is going on with your A:F ratio, fuel pressure, and N2O pressure just to be safe. And with the cam and lifters I would also recomend upgrading the valve springs which means new valve locks and retainers as well as installing a double roller timing chain. Once you do all this then at that time you may need some larger injectors but the stockers would still probably be enough untill you upgrade the intake manifold and port the cylander head. By the way, you could port the head yourself for less than $75 if you already have the tools and that would net you at least an additional 10hp.
