Interesting topic.
Did you have a theme or interest area to start the social networking site for?
Here are some thoughts:
1 how much does it cost a month to run a site like myspace?
a) Social Networking scripts can range from being free to a few thousand dollars. If you get someone to code it for you, it will easily run you in the low thousands and upwards.
b) Anywhere from about $30 to $300 (monthly recurrent for shared hosting to VPS, to dedicated server hosting)
c) Traffic generation costs - depending on your "recruitment" rate, you might want to actively generate traffic (free or paid) until you get to a critical mass or unless/until the existing members can help you generate sustainable (profitable) levels of traffic or recruit new members adequately.
d) Cost in terms of your time (e.g. if your hourly rate for doing any other job is $100 / hour, then spending 10 hours a week maintaining/moderating the site will be costing you $1000/week).
2 what kind of servers do i need?
a) Depends on the i) script ii) number of members iii) whether you have resource hungry components running, i.e. image upload and storage, audio and video upload and storage, live chat or even video chat features). Higher end site probably have to worry about the server as well as the bandwidth costs.

Good thing is that you can scale up as go along.
Small tightly niche focused social networking sites without too many bells and whistles should be able to run off of a shared hosting account just fine.
3 do i need to hire a bunch of moderators programmers and staffs to successfully run my site?
a) Depends on how much time you have, the theme of the site, how much automation is available etc. etc. etc... but "showing" a presence periodically is probably a good idea (think "Tom" from myspac3) and if you are making any profits off of the members.
You might want to try using Boonex Dolphin, which is free and mess with that a little bit, just to get your feet wet.

After that, you could scribble a plan on paper:
a) Your theme/concept for the social networking site
b) How you plan on populating the initial critical mass of members (e.g. 1000 active members; 2000 semi-active members, and another 2000 somewhat active to dormant members).
c) How you plan on getting traffic to the site (b, c, and d are probably related)
d) How are you going to "convert" visitors to actually sign up and become a member of your site? (e..g can you leverage on existing social networking sites or forums say you make friends on myspac3 with a bunch of dog owners and you set up a social networking site for dog lovers and invite your myspac3 friends to your new site).
e) How you plan on getting members to keep coming back and posting.
Another idea is to use a wordpress blog and manage it as if it is a social networking site. (this would be cheaper and easier to manage

although some folks might disagree on this idea. In a way, it also depends on what your mean by "Social Networking Site" because it could refer to different things to different people)
Perhaps other members can share their thoughts and ideas too?
Cheerio
