Welcome to "this life!" My roots are on Head-Fi, and the saying there is "Welcome, sorry about your wallet!"
Yes, you absolutely can connect these to speakers. I made an explanation of what each component in an audio system does, and what an upgrade to each component brings as improvement. A nicer DAC would benefit speakers, and the headphone amp would provide volume control to active speakers that don't have their own dial... but this doesn't have enough power to amp speakers by itself. "Active Speakers" are speakers with a power amp built-in, or you could separately buy a power amp to use with any passive speaker.
Clearer?
Not to my knowledge, my unit outputs to all outputs at the same time, including all headphone outputs. This can be handy if you want to use more than set of headphones at a time, but keep in mind that there's only a single volume control for the headphone output. This works pretty well for 2 sets of the exact same headphones, one using 4.4mm pentacon and one using the XLR output.
