More info on this please.
Ok, an adapter like this will allow you to use an old Pentax screwmount (M42) lens on the Canon, which gets my vote for most plentiful and cheap great glass. Look around for things like Pentax Takumars, which are quite simply some of the best lenses ever made, and you can get them as cheap as $10. Carl Zeiss also made, and still makes, lenses in this mount. You can find other lens mount adapters, just search for "EOS xxxx adapter," where EOS is the canon mount, and xxxx is another brand, Nikon, Pentax, you name it.
Finally, when shopping for a new AF lens, you don't have to restrict yourself to the manufacturer's offerings. Like I said earlier, the Tamron 17-50mm f/2.8 is killer sharp, and I got a really nice used example for $250. If I was looking for a telephoto, I'd look at the Canon L 70-200 f/4, or maybe a 3rd party lens maker.
For a flash, in Canon you have lots to choose from. If you want to go wireless, with the flash off the camera, you can either do it automagically with Canon's system, using compatible flashes only. Google 580EX and 420EX for current pricing, I would think a full system with flashes, light stands, umbrellas, transmitter, would probably cost $1000+. I used just this system this weekend, and while it did all the thinking for me, the results are all over the place and you have to do a lot of tweaking to be happy, and the flash units have to be oriented so they can "see" each other, which means indoors it only works up to about 30 feet tops, outdoors it often doesn't work period.
You can also go manual flash, which is a lot cheaper and more reliable. Problem is, it doesn't do any of the thinking for you. You have to learn flash ratios, angles of light, falloff, all that good stuff. You can use any flashes you want for this, as long as you can dial down the manual mode, so a flash costs $50-75. You'll want some way to pop the flashes, and the systems most pros use are pocket wizards, quite expensive. There are other RF options out there, ranging in price from $20-$300, so look around.
Look at Strobist for a great resource in off-camera lighting. You can spend weeks months there though, I'll warn you.
