Thanks for the responses. Maybe now I can start figuring out what to do with some of this. Here's a straight down view of this stuff (a few extras in this picture) and I didn't re-size it down too much so you can see extra detail.
I still couldn't get the writing on the boxes/relays (flash-glare, no flash-too dark), so I'll just tell you here what they say. And by the way, I believe I might have looked up the "OEG" things by the 'PCD...' numbers and saw that they were relays, but I'm still unsure about the small light blue thing.
Black:
OEG
PCD-124D1M 24V
10A 277V
15A 125VAC Res.
10A 250VAC Res.
Blue:
***Almost identical info; either way blue and black are the same thing just with different amps and volts
Small Light Blue:
***Mainly jibberish on the side (lol), but the top says "100nM275V~X2
PCX2 335M MKP"
