1) No, a different kind of data. Basically, you can get the actual window size used for sending on each packet (and also see the round-trip time between the packet and the ACK for it), and the packet retransmits that cause the window to collapse. Well, you'll only see the window size advertised from the receiving side directly but you can compute the send size by subtracting the last ack's sequence from the last data's sequence.
BTW, the easy way to see the retransmit is to use the plain old command-line FTP with the hash printing enabled (it will print "#" for each block of data sent). You'll see these hashes printed fast when the data flows nicely, and hiccuping when a packet gets lost.
But PingPlotter's data is useful too. Traceroute ("tracert" on Windows) would probably give the approximately same information. It looks like Comcast has some kind of issues where their network connects to another provider, with the delays and packet loss.
2) The network card in your computer. BTW, the other side also has its settings for the maximal windows sizes, and the smallest of the two gets actually used. So your increasing the setting on your side might not help at all if the other side already has the lower limits.
