Ok, Time to take a crack at this

How can i hide my IP/Hostname on IRC?
1.For this question I agree with everyone else, Proxies. Shouldn’t be too hard googling it returns plenty of useful results and lists. Not sure how reliable this is but this looks promising http://www.multiproxy.org/ .

I have an open port (1025) Is this bad?
2.The open port doesn’t seem like to big of a deal in itself. That specific port is registered to network blackjack in both TCP and UDP. If the open port does bother you could consider getting a software firewall or amending your current firewall rules to disallow this communication on that port. In the event you need a firewall I recommend these free firewalls.

Sygate- http://www.sygate.com/
Outpost- http://www.agnitum.com/products/outpost/
Kerio- www.kerio.com/
Any of these should do the job nicely

When i connect my router/Modem it connects but not to the internet, It says connected via usb.It can download but not view IE things, What can i do?
3.I’m not totally sure I understand this question, so instead of leading you astray I will leave this one alone for now.

Hopefully this is helpful
