My engine bay

I'm looking on cleaning up my engine bay, and making it look nicer. Any ideas on things I should do? I'm not looking to make it all shiney with chrome or anything. I like the black wrinkle, machined look. I'm thinking of removing the heater hoses , and getting some plug wire looms and new plug wires. Also looking at hiding some of the wiring or at least making it look nicer, any ideas for doing that? I'll be wiring in a new set of Autometer gauges maybe next weekend, so I'll probably work on the wiring then. And the vent tube on the passenger side of the engine bay, can I get rid of that or should I just leave it? It looks out of place and people always ask me why its even there.
