I think you and me are on the same wavelength. I've been researching dropping Comcast for the same reason, though my triple play is only 150 (I'm betting you got the better package, I was to cheap :biggrin
Phone - Magic Jack or Ooma. Like 3.00/month. Ooma website has a zip code evaluater as actual cost varies based on zip code (local taxes) but its still dirt cheap. There is an upfront cost to get the Oma hub (120ish), but the long term savings is the goal. I don't do international calling so I don't know about that, but you could look into Skype if thats a concern. Both options need high speed internet, and if you want home security like Brinks, using Ooma or Magic Jack may or may not work depending on who you listien to on the interwebz.
Internet - Best bet for me is still Comcast. There are other options, but speed matters to me, and DSL in my area is slow and not much cheaper. I've looked at clear but I don't get great reception. Since my future TV/phone will be based on using my internet connection, I don't want to skimp. When you cancel phone/tv, act like your gonna cancel internet too unless they put you on one of those reduced cost for 6 month deals. Couldn't hurt to try.
TV - your already on the right track. I'm not sold on Apple TV, and Google TV remains to be seen. I like the blu ray option as apps can be added should something new come out, but you get the bonus of a DVD/Blu ray player. I myself have not yet upgraded my DVD player, so its a win/win all the way around.
Local news - Either get a digital converter and/or antenna to pick up local free broadcast channels. Not a lot of selection, but should be able to get multiple local options for news. Not an always on CNN type option, but the net can fill in for your news hit whenever you get the urge. Also, Blu ray players have apps for various content, so news is likely one of them, but I don't know if you can select a local option, or be saddled with national coverage.

55 - Comcast internet
3 - Magic jack for phone
15 (ish)- Netflix
10 - Hulu plus

83/month -
220 - 83 = 137/month saved
-----------------------------------
You have to factor in hardware costs (blu ray/apple tv/Ooma hub/antenna), but even if you spent 500.00, at 137/month, you'd break even between months 3-4, plus at that point you'd also have all the hardware. My .02
