If you just want to go with a visual calibration of your screen for now, the only thing I could really suggest is going to google images and searching for "calibration images", and adjust your monitor's brightness, contrast, temperature, and individual RGB controls (if it has them) until you can see all of the various gradients complete ranges.
Usually you see Black to white, Black to red, Black to blue, Black to green (or more) in a dozen or more different shades, and you just adjust your settings until you can see all distinct shades in each of the gradients.

this sort of thing, or

But, you'll never get it truly accurate by eye, so keep an eye out for EyeOne bargains. They do come up on sale at various places fairly regularly.
You only need to do a printer calibration once for each type of paper. I only use the Epson inks in my Epson printers, so I know if I calibrate it with Ilford Smooth Pearl now, I won't need to do it again, and it'll still be just as good with Ilford Smooth Pearl a year from now. A lot of the time, your printer manufacturer will even have ICC profiles available for you to download (or the paper manufacturer). So check their websites.
