Where to start, Woolie? Have you Googled on Chinese recipes? I'll bet you'll get some great stuff right off the bat.
I don't really have any recipes to give you, because we stir-fry with an adventurous attitude and the willingness to use stuff that is on-hand. If there is a left-over piece of cooked steak or roast or poultry, we often chop that and brown it in hot oil with vegetables. If it's rare meat, then we chop it into reasonable-sized pieces and cook it in the wok before adding the vegetables. Try to leave the vegetables "al dente" so they've got some crispness to them. This contrasts with the texture of the meat and the softness of the steamed rice. The great thing about a wok is that it is versatile, and doesn't require a lot of cooking oil.
Vegetables we use commonly include onions, minced garlic, carrots, green peppers, green beans (in season), shredded cabbage, mushrooms, etc. It's not necessary to buy special Chinese produce to whip up a nice wok meal.
For heat, you might get 'hold of a bottle of chili oil, or use cayenne, crushed red pepper, or a spicy curry. I've got access to MANY kinds of hot sauces and relishes because I make my own, so heating up the dish with chili products is pretty wide-open.
