Below are links to three solders I've found very easy to work with low melting points, great flow, etc.
Just pick a soldering station that fits your budget.
keep the solder tip clean/shiny (with a damp piece of sponge) and tinned.
Use miniature alligator clips on component leads and to block heat from toasting anything that would suffer from the same..
Make as secure a connection (metal to metal), as possible, before applying heat, while touching both pieces, at the junction to be be soldered.
Remove the soldering iron tip, as soon as the solder flows into the joint, to further avoid any component toasting.

The copper clips are excellent, but: the shiny minis work well, to sink the heat, also:
Enjoy the learning experience!
