AVarley Loc: Central Valley, California

I am a regular at Yosemite and like a basic 55-250mm lens to "walk around" most of the time. It's got decent range and will give good results.
PS: Dont forget to look around outside the lens too! It's a spectacular place ... I hope you've planned to stay a few days there and explore. Have a great time!

I go to Yosemite about once a month to shoot the ever changing beauty. I take a 18-105 and 70-300. My main shooting lense is the 18-105 for landscape. Here are three shots to give you an example of the landscape you might see. Followed by a couple more of aminals in Yosemite.

Walk-around lens for Yosemite: Canon 18-200 IS (that covers your canon EFS 15-85 & EFS 55-250). For Telephoto, get a prime somewhere between 300 - 500. Unlikely you'll need wider than the 18, but if you're fretting, get a Tokina 12-24. If you think you'll need Macro - then get the Canon 100mm (you've already got that). The 18-200 will catch 85% or more of the shots you'll want - without having to change lenses (will need tripod if shooting at night though)

What time of year are you going? If going in the winter, I'd suggest getting some spikes for your shoes to handle the ice, especially around the waterfalls.
(ex: http://www.amazon.com/Rubber-Durable-Diamond-Fishing-Carabiner/dp/B004TJE9QO/ref=wl_it_dp_o_npd?ie=UTF8&coliid=IYH94DDLU2R24&colid=3THBD6ZS7JHW7)
And a monopod (I have a Manfroto on order that is supposed to be strong enough to use as a walking stick as well) because tripods are a bit much to be hiking with.

If winter, I doubt you'll need the macro unless you want to catch photos of snowflakes. Personally, I bring everything and leave the un-necessaries in the car, to fetch in case they become necessary.

Here's a YouTube video link to Yosemites' Nature series, I'd highly recommend watching all 16 episodes to really get a feel for what you're walking into... of course, even the video cameras can't capture how magnificent the place is.

If you are going this month, I'd strongly recommend watching the one on Horsetail Falls, it's spectacular this time of year.

One last thing, these come in really handy too:

You can open a couple, put them in your camera bag in the trunk to keep your equipment from freezing... and of course, use them to warm your hands and feet :)
