The best tips I can give are to check out some of the posts already floating around on this forum. You can also check various resources and videos like my website, among others. Carp fishing, like most aspects of the sport, is as simple or as complex as you want it to be. Learning more only increases your results and understanding this, often misunderstood species can lead to some fulfilling trips to the banks.
Lets start with baits;
Boilies, what are they?
Dough Baits
Particle Baits
Rigs...
The Hair Rig
Starting Carping
And for example here is a good video from last spring from the Merrimack river

Right, that's a good place to start. Maybe you know some of it, maybe you don't..but it is a good amount of info in one place and that is always a good starting point.That being said lets get to your questions as well.
You got it right, the spawn is gonna be on us soon enough. Once the water hits mid 40's they start heading to spawning areas and around 60 degrees will start spawning. These can be good targets early spring but once they actually start spawning forget it. The process usually involves 1 female to up to a dozen males competing for the right to pass on their stuff...and they are focused on the job. They will not eat while spawning, and many fish lose weight during this process..both sexes. Some from eggs and some from the energy spent without eating for possibly days on end. You can still catch fish in spawning areas, but most of them are younger or the odd not spawning, early/late spawner etc. Doable but maybe not the best bet for action packed days during the actual spawn. Not too mention all the bonus goo that fish tend to spurt when caught during this time...
The benefit of the hair rig is that it is designed to work with how the carp feed. Carp have phalangeal molars. These are basically hardened areas in the back of their throat capable of crushing all sorts of food items. The way in which carp feed, from any water level is too suck food items into their throat, crush/chew them up and swallow them. The hair rig works by llowing the carp to suck food items in while turning the hook down into the lip..when the fish swims off it sets the hook resulting in safe and secure hook sets. When a carp runs on my lines, I know it isn't going anywhere.
That said the hook pulls you mention sound more like your putting too much pressure on the fish at the bank. You cannot simply drag a large fish up on the rocks. You need a large adequate net for the job and preferably a mat to lay them on instead of the rocks which can cause serious harm to big fish. The common practice is to fight the fish until you can keep its head on the surface, then slowly pull it over the net in deep enough water that your not dragging the fish along the bottom, then raise the net upwards securing the fish. I hope that makes sense..heres a pic of what I mean...
Carp prefer 2-10 feet of water..however they can be found at all depths. They are a warm water fish and thrive in water temps of 60-80 degrees...though they can be caught in much much colder water..it is very tough though and not for the light hearted.
Someone mentioned above about light line. DO NOT USE light line for carp. Carp are line shy yes, but they are very strong fish and will break light line and tackle quite easily which just puts the fish in harms way later having to be dragging along line and hooks etc. There are better ways to camo your lines and rigs to fool them..most carp fishermen do not go below 12-15 pound test mono, though some prefer higher braids. Serious damage can also be caused to the fish by having to tire it out far more then necessary on light tackle. We have a responsibility to use adequate line and tackle for the job.
Anyway I am off for some coffee but I hope that helps a bit..hopefully we can get some time on the banks together sometime soon and I can show you some tricks...
