Having just completed this process myself I'll try to help. Of course we must start with the "calibration and profiling aren't the same statement." Having disposed of that...
As to your monitor it is hard to say without seeing it, or the feedback from a calibrator. I just received my NEC 2190UXi with the SpectraView II software. I was amazed how far out of whack the bundled software with my Monaco XR was compared to the SV II. Probably the best thing to do is buy the calibrator/profiler and check out the condiiton of your monitor.
If you decide to get a new monitor you are pretty much going to be limited to LCD; the parts necessary for high end CRTs are not being made anymore. The next thing you run into is LUTs, or Look Up Tables, for the monitors. More bits mean smoother displays, and many of the higher end monitors have hardware access by one means or another to the LUTs on the monitor. How much all of this is marketing hype I haven't been able to determine.
As to the display itself generally the quality goes IPS->*VA->TN. A good article can be found here:

LaCie, NEC and Samsung all make good monitors at a variety of prices (being a mac fan I just can't recommend Dell ). It depends on what size you want, how much you want to spend, and what features you desire. Models? Try Eizo CG or CE series, Lacie 321, NEC xx90UXi (up to 26 inches!), Samsung 214T or 244T (given the original price the 244T looks like a really good buy). Samsung has also released the XL20 with LED instead of CCFL lighting (if you can find one) at a great price for LED monitors. Give a really wide gamut (All the Adobe RBG space if the press release is to be believed.) All will cost over $1000 (the Eizo CGs are mostly over $2000) except the Samsung 214T/244T. Some come with their own calibrators, others can use different brands (Optix, Spyder, i1).
Take your time, do your research, and you will find they one for you.
