I am proud Ketan.
Here are my recommendations:
1. DEFINITELY go hard wired. If you want a slower network with disconnects, etc., then go wireless.
2. I would always recommend a server. But, that doesn't just mean purchasing a Dell T410. You need the OS (please SBS), and the abilit to set up a domain.
FYI: I don't know why it is so expensive to set up Ethernet cables. The best thing to do is find a local college with computer science or networking classes. Ask the professor if there are any students who want to make a little extra cash. I paid three students $8.00 an hour and they set up the whole network topography in six hours for that price plus pizza.
FYI2: Always, always, always do two drops for every one drop you need. You may not think so, but eventually you will need another Ethernet jack. So, one run takes two hours, the other five minutes.
