I've used lead-free solder on multiple occasions. It adheres significantly worse than lead-tin eutectic, but also doesn't smell bad and (presumably)
doesn't cause lead poisoning to underpaid workers in Apple factories.
I'd recommend getting EagleCAD to those who want to invest their time in creating circuitboards - last I checked, it's free and does a ton of
the work for you, including optimal path-generation.

I'll throw my hat into the ring. 
If you want to learn electronics, first understand DC circuits. Resistors, capacitors and inductors (chokes, transformers...) behave differently
with DC as opposed to AC.
Study up on Kirchoff's law,Thevenin and Norton's theorems.
Resistors are linear devices, and are governed by Ohm's law.
Take a look here: https://www.electronics-tutorials.ws/dccircuits/dcp_2.html
They are labelled with color bands that give you the value.
Here's a nice color band calculator, provided by DigiKey
https://www.digikey.com/en/resources/conversion-calculators/...
Both capacitors and inductors behave exponentially with DC; After roughly 5 time constants, a capacitor becomes an open circuit (Ideally)
An inductor becomes a short circuit after 5 time constants.
For capacitors: https://www.electronics-tutorials.ws/rc/rc_1.html
For inductors: https://www.electronics-tutorials.ws/inductor/lr-circuits.ht...
AC is a different story. Now we have reactance and resistance playing together.
For capacitors: https://www.electronics-tutorials.ws/capacitor/cap_8.html
For inductors: https://www.electronics-tutorials.ws/accircuits/ac-inductanc...
This seems to sum it up nicely

I would recommend that you invest in a good multimeter. I have a few of them lying around the bench.
If you're just starting out, get an inexpensive meter.
Just in case something goes wrong. 
For parts, take a look at Joe Knows.
https://www.amazon.com/Joe-Knows-Electronics-Value-Resistor/...
ebay is also a good place to look, but you have to be careful. You could end up buying a lot of factory rejects. (Been there...done that)
For hand tools, that's up to you. I have an inexpensive set of pliers and cutters, and I have my precision tools.
I build guitar pedals as a hobby, so I build my prototypes with #28 gauge kynar wire wrap wire.
Take a look at erem tools. Some of the finest tools ever made. Also, look up weller xcelite. Top notch tools for servicing.
If you're going to build prototypes, invest in a temperature controlled soldering station. Too much heat is a nono, and can fry semiconductors.
Definitely worth the money.
If I can help, please let me know.
