I have several soldering stations and use either Cardas solder or Wonder solder. If you live outside of the Boston area I'd be more than happy to help out. Just PM me.
You got good advice on what to use. My question is, Why? Before you go applying a lot of heat it is good to know where and what and why? Because you can buy all the greatest gear, and then if you don't know what you're doing easily overheat a trace and trash a circuit board.
My advice is once you get your stuff take a few wires twist them together and practice soldering. Get a feel for how heat flows into metal and how solder flows to the heat. What you want is to get the part hot enough all you do is touch the solder and it flows right into the joint. But not so hot it starts melting plastic and insulation. Takes a little practice to get the hang of it which is why I suggest start with scrap wire not expensive preamp.
