Why yes you should.
All kidding aside this is a very good lens which should do quite well with your camera.
Here is a test from Photozone.

I used it and its very good, no hesitation, it will fit very well with your kit.

I've even got the fairly un-great EF 75-300mm IS lens (the all-time first IS) which I bought almost immediately before the newer and much improved 70-300 came out. I'm happy enough with the old one to have stuck with it, but if I were faced with the choice between the very nice EF-S 55-250mm IS and the older EF 70-300mm IS, I'd buy the 70-300 right now. There are also some bargains in the L lines in this area, but you lose some focal length and even IS, and I'd always get the IS where I have any choice at all.

You already have an IS lens for dimly lit interiors. Telephotos are not usually used in scenarios where IS is required. Also consider the Canon EF 70-200/4 L for only $100 more, for superior image quality.

John,
I disagree that telephotos don't need IS. If anything, telephotos are the exact class of lens that benefit the most from IS. Reducing camera shake becomes more and more critical as focal length increases.

I use my 70-300 for landscapes as much as I use the 17-55. So in taht instance I would say that IS is more useful on the 70-300 than it is on the 17-55.
I think the 70-300 is worthwhile getting. The 55-250 is lighter and more compact but apparently not as good quality as the 70-300 (I haven't used the 55-250). So what compromise you want to make - weight or ultimate image quality and much of this depends on how you will view the images. Will it be on monitor, or print; and if print, what size? Viewing on-screen or prints up to 8x12 the differences will be much less than you imagine.
Have a look at this site which compares them: http://www.the-digital-picture.com/Reviews/Canon-EF-S-55-250mm-f-4-5.6-IS-Lens-Review.aspx
Remember that the phot example on the review page is equivalent to a print about 5 feet wide!
