This post would get a better response in the 'Building Your Own Stompbox' forum--you may want to PM Aron to have it moved.
Also, those are some pretty intense projects you've got listed there--I'd guess that you're fairly new to building based on your request (please don't be insulted if I'm wrong on that...).
If I'm right, you may want to put that list on hold for awhile--even if those builds are ones that you want on your pedalboard asap--in favor of building some simpler projects first.
That said, here's a more appropriate answer to some of your questions. I don't have Mouser parts numbers for you (I don't order from them...yet), but I can tell you that when it comes to capacitors, ignore the hype. All of it.
Use poly or ceramic when you need to be precise, use electrolytic for larger values or when you need 'enough' capacitance, but not any precision, and don't use tantalum unless there is absolutely no other choice.
