... I strongly advise you to pick up a copy of Mad Bean's Eagle libraries, they have only the parts you want to use, no extra SMD parts :)
Yes, I definitely use the Mad Bean Eagle libraries.  It's saved me a lot of confusion.  :)

I think I'm asking this question in a very confusing way. To clarify, are there general guidelines to choosing a type of capacitor beyond the available capacitance values and voltage ratings? 

Are there brands to avoid, or brands to choose even if more expensive?

Transistors/MOSFET/JFET anything to avoid or are they all pretty much the same quality?

Also, when I look at a finished schematic I suppose I could just type the package number into a search but then I get thousands of choices. I guess I'm asking if there is a better and more efficient way to go about both choosing and shopping for components.

Each package in eagle should have properties that should show lead spacing and package size. Is that what your needing.
I just don't know why to choose something like "R01005" instead of "R0204".  Right now I'm just placing the proper symbols on the schematic.

When I'm putting together a schematic I can make it look nice and correct and it checks out electrically but then when I want to lay out the PCB I have to make sure I choose the correct footprint.  Shopping for components is also confusing.

I think the issue is I don't know how to differentiate between the different parts of the same value.  I guess in Eagle it's called "package".

Is there a tutorial concerning choosing the package for the PCB layout and shopping for the components?

Before I was directed to this forum I wanted to build a treble booster for my pedalboard.  I found a schematic and PCB layout on fuzzcentral and used the laser printer toner transfer method to make the board at home.

I'm liking the sound a lot. :)

The inside is a mess because I didn't consider the size of the jacks when picking the 1590a but I got it all stuffed inside (rather sloppily) and this was the first time I touched a soldering iron in probably 28 years so that's not so nice either.

Next one will be better though.
