To answer your questions:
CPU usage -On my 2.4 Ghz machine, it varies between 0 and 1%, 70-80MB for memory usage.
Windows7 - I've run it on XP, Vista, and 7 without problem
On all the time - you'll only get credit when H@H is on and running, of course. If the machine is hibernated, the host site will lose contact with it and mark it offline, as opposed to a firewall problem(which I've had a few times).
Already running a torrent client - I've run both at the same time before; generally I find torrents to be less well behaved than my H@H client. You'll just have a lower transfer rate(and therefore less gold/hath return).
Choosing a port - Pick one at random, preferably somewhere between 1k-65k. Roll dice if you want. Just avoid ones you might already be using(thus going above 1k to avoid most of the common ones). You can use this [
en.wikipedia.org]
Wiki list of TCP and UDP port numbers if you're hesitant. Then just set up port forwarding(you might want to switch your computer to a static IP address, it was my biggest cause of firewall issues).
It'll be used, if mine is any way to judge. It depends on how much bandwidth you have left over your torrent client.
Plus, you can set the site to use your H@H client while browsing - results in fast loads if it has the images cached on your own machine. To force that, simply hit the H@H download button and save the resulting file to the hathdl directory. That will not only cache it for the browser, but put it into a sub-folder in the downloaded directory.
With my client, normally I only have to do that and let it sit for ~5 minutes for lag-free browsing.
