Most hardware firewalls (usually part of a router) require either a LAN or USB connection to the modem. Since most PC users have internal dial-up modems, then that won't work. Use a software firewall for dialup.
. Re. Norton IS - you have my sympathies. It is the most resource hungry and intrusive stuff you can use. Making up your own suite is a far better idea. I hope you either didn't break the seal if retail or bought it OEM for cheap. Current recommendations are:
Kaspersky or TrendMicro's PC-Cillin for AV (annual sub.) You can keep several AV softwares installed as long as you use the real-time features of only one. And there are also the online AV checkers that you can use for backup from TrendMicro, Symantec, Panda et al. It looks like the combo of Kaspersky and NOD32 would be the most thorough, but Kaspersky alone is darn good ( however, I've heard that their tech support can be frustrating) - see
http://www.AV-Comparatives.org for some good analysis of AV SW.
Sygate personal firewall or ZoneAlarm Personal (free) - I prefer Sygate as it isn't as intrusive or as hard to remove as ZA.
Spybot + Adaware + M$ beta anti spyware (all free, at least for now) - run them in SafeMode for best performance. I use all three but use the real-time features of only one.
CCleaner (Crap Cleaner) - does as its name implies. Cleans the crap that accumulates on your hard drive from Internet activity, etc. It helps if you have a fairly good idea of how things should be before using the more advanced features of CCleaner as it's not hard to get rid of something you might need.
