Utorrent Help Peer/Seeds ???

Hey I just wanted to know, I started uploading torrents for people and I really hate it when ppl don't seed because I need to use up my bandwidth to get it on the net and even continue after. So I would like to see other people seeding so that I can stop seeding the torrents and continue uploading new ones.

Now my question is is there a way to find out if people are seeding a completed download of the files??

I have seeds x(y) and Peers w(z)

The x is the number peers I'm connected to that are seeding to me and y are the number of total seeders. ( Thats what I assumed, please correct me if I'm wrong)

w would be the number of peers that completed the download and the z are the number of seeders and leechers (or just leechers, thats the one that confuses me the most)

Again those are just assumtions I would love and appreciate a clarification.

One more question would be the availability, it starts at 1.00 while the ratio starts are 0.00
if the Ratio is over 1.0 and does it automatically mean that the torrent is now download by some1 or can it meant that I just uploaded that much data.

The availability is 4.xxx sometimes and when I stop seeding it goes to 1.00, that doesn't mean that its no longer available does it??

I hate this. I'm not a noob when it comes to computers, but I'm pretty new when it comes to learning about uploading/downloading torrents and how it works

Thank You for the replies if there are any
