.030" 60/40 rosin core is what I used for all the switch and component soldering I do but the tin/copper will eventually replace all of the lead content stuff. My wife works for a company that assembles boards in and SMT machine then solders the boards with a solder wave machine. They have been using lead free for quite a while. They coat the different boards using several methods and different forms of resin to keep corrosion at bay. The boards wouldn't last long if they did't coat them.

I always tin a wire with solder before I solder it to a component. This way you know it is clean enough to get a good stick. If you can't tin it then it's too dirty and needs cleaning. I only solder stuff when there is no other way. A soldered joint will work harden at the joint and the wire will eventually break if there is vibration or movement going on. I use crimps for as much as I can but they aren't like the ones you buy at the auto parts store and some are pretty expensive.
