I've always had a rough time with those pesky court cards as well. Everytime they come up in a reading, I think "urghh!" or something else inarticulate. I guess the main problem for me is that they don't do anything. I look at the RWS Seven of Swords and I see a guy making off with a bunch of swords. Okay, no problem, he's being a thief, he's taking a risk, trying to get away with something, being clever etc. etc. etc. Or with the Two of Cups, you have a guy and a gal making moon eyes at each other over a cup. Once again, no problemo. Romance, friendship, partnership, etc. etc. etc. But when, say, the King of Whatever comes up, what is he doing? He is just sitting there, defiantly (as I see him, anyway). What the heck do I do with a guy who is just sitting there?
There is one thing that helps me a little when using a court card as an advice card, rather than as a person. When a court card comes up, for example the Queen of Cups, I'll ask myself, "What would the Queen of Cups actually be doing in this situation?" Then I'll visualize her getting off her throne and taking some action that is consistent with how the Queen of Cups would react. It is that mental image I'll work with or refer to in the reading.
BTW, I would like to second Skydancer's recommendation. Mary Greer's book on the courts is excellent.
