Always make sure you are connected to a secure network (look for lock icon in address bar) before entering any sensitive information, (credit card, bank, social security, etc.) and even then, make sure it is a known and trusted site.
I would use the default settings for your firewall. Setting them too high can cause problems.
I personally would avoid P2P sites, they are a well known path for malware infections.
Orbit Downloader seems to be ok, don't know much about it, though.
