I don't think 1 is correct because that body's coted in epoxy(but it's not mica either). I thought #2 were voltage regulators(the ones i have have voltage marked on em some in dc, some in amps). Does 4 say relay on it or does it give a uf number(ie: .2uf). If it says relay on it it's a relay, if it says uf(unifarads) it's a block capacitor. That small silver thing on your question list looks like a controller crystal(operates at a certin mhz to control a function). That black cylinder looks like a resistor of some sort(have a bunch of em from some ham radio equipment and pc power supplies - their closer to a watt resistance I believe). That IC attatched to the heatsink and the one next to it look like regulators of some sort(not sure what) and that square looks like a surface mount capacitor. The chips in your last pic are machine soldered with high-temp solder and aren't worth getting off the board(i've tried getting them off with a butane torch and while they do come off, the torch ends up leaving scorch marks and rendering the rest of the board useless).
Just my 0.02 on the subject,
Matt
