Question about dropping services prior to contract end date

Could someone explain how Comcast handles this situation from a billing perspective:

I am under a two-year contract with Comcast.  I purchased a triple play.  Due to the project cost increase after my contact ends this month, I decided to Port out my home phone.  I was told that it could take two weeks to Port, so I did it slightly more than two weeks before my contract was scheduled to end.  It only took a few days to Port, however.  Now I have 13 days left in my contract, but I don't have phone service any longer.

Questions:

1. Will I have to pay an ETF since I don't have a triple play any longer?

2. I already paid my bill for a triple play until the end of the billing cycle.  Since I dropped phone service with 13 days left in my service month, how will that affect pricing?  Will I actually owe money since a bundled price is often cheaper than buying components separately?

3. If I drop TV service at the end of the upcoming weekend (one week before my contract ends), how will that affect my bill? Does Comcast offer partial refunds, or would I actually have to pay more since I dropped down to one service and l wouldn't even qualify for a double play at that point?

For reference my triple play price, after taxes and fees, is about $150.  It was projected to cost more than $200 after the contract ended.

I will be switching to Verizon for Internet only.  I will use my cell phone for calling and an antenna, combined with a Roku, for TV.
