Regarding care, you can assume the plant likes lots of light (like right on your sunniest windowsill). Water well when the soil is dry, not much sooner. There is no great advantage to leaving the soil bone dry for any extended period. Maybe move the plant to a pot one size up, since it seems to be running of space, but not a whole lot bigger. The pot should be wider than deep, with holes at the bottom. Use a fast draining soil mix. Do not water for a week after repotting, to avoid complications with rot. Hopefully that gives you a place to start. Enjoy your new plant!
