Can anyone help me understand the "connections" info in LW?

I used to have LW basic but recently got pro. So now I'm connected to 5 Ultrapeers all the time, but I still can't really tell which each is by reading the text abbrevations in their names.

Also some stay connected for over an hour, others keep changing.

What helpful info. does the in/out dropped %s give?
What helpful info. does the bandwith give? It seems to change by the second.

I've read the guide, FAQ etc. but I'm still confused (and have been for 2 years.)

Is there a book or something on the web that explains such things? I connect via a dial-up modem which is satisfactory for my purposes, but it would help to understand the whole bandwith and how it's divided up question.

Finally, I been leaving my machine available for uploads at 100% and with 3 slots and there have been a surprising number of successful uploads but I haven't been able to keep track of how many? Is there some way LW keeps this info.?

TIA to anybody who can answer these questions.
