Help with replacing 2000 Century PCV hose

[Andy87]

So, my intent was to replace only the elbow of the PCV hose, which was totally cracked, instead of the entire PCV hose, but I accidentally snapped off a piece of the hose while I was removing the PCV valve in order to remove and replace the elbow. Now I need to replace the hose, which seems like a simple process in itself (just pull out the 3 connection points and install the new hose by pushing in the 3 connection points, right?), but there's some stuff in the way of the hose that I will need to loosen/remove in order to pull out the middle connection point of the hose circled in red.

The things outlined in this next photo are blocking the hose from being removed immediately, but I feel I'll be able to get away with not removing the hose outlined in yellow. Can anybody with experience in this matter let me know what I should remove in order to remove the hose and how I should do that? I don't want to ruin anything (I'm not a professional at all), or else my sister and I will be stuck walking to school like normal kids. I would really appreciate it (and so would my sister). 🙂

I could always buy the Haynes manual, but I've already purchased $15-20 in parts, so some volunteer help would be seriously appreciated.
