Take a look through this

http://www.sea-angling-ireland.org/bait ... %20lug.htm providing you haven't already done so, it's quite informative for a beginner. As for brands of line, hooks etc, everyone has there own favourites, I've learnt from trial and error what suits me best. I don't think there would be too many that would argue against daiwa tournament or ultima powersteel, both very good lines. Do not by any means use a 4oz lead without a shockleader, your looking for trouble if you do, general rule, 10lb of breaking strain per 1oz of lead. Ensure your rod has a casting rating capable of handling leads on the upper end of the scale like 4oz plus. I use ultima powerflex tapered shock leader, 15-60lb, again there are plenty more to choose from. Hookwise my personal taste is kamasan aberdeen b940's, again its a personal preference, they come in small quantities so you can try out a few different makes to see how you get on and what you like best. I would recommend a size 1/0, will pick up almost anything on this hook size. Bait can depend on what is readily available to yourself, lugworm is a pretty good all rounder I find and is easily obtained, but you may want to begin by buying bait from your local tackle shop if they provide such a service. Have a good trawl through this site, you'll find plenty of link to helpful sites with rigs etc, +1 on the animated knots by the way. If you come across any anglers out and about don't be afraid to ask any questions, most will only be too happy to help you out. Hope this is of some help, not easy answering everything in one go, any questions just keep on asking, someone will be able to give you an answer.
