Hey Kenneth,
you have many questions which I'd highly recommend you ask in the openHAB forum. Over there you'll meet a ton of users able to answer everything.
In short, I think openHAB is perfect for your application. Low level is where openHAB can shine (other than most proprietary solutions). Here's one example where you can see all that in action. A command is executed, the output further evaluated and a nice view is generated for the openHAB frontend: https://community.openhab.org/t/7611 - you will find many more Example implementations using external tools and scripts in the forum.
Regarding VNC or HTML5: Let's say "non of the above". openHAB provides a Web UI for general administration (Paper UI) and the end user control frontend (sitemaps in Basic UI). Besides that configuration and scripting is mostly done in configuration files which you can edit via the Samba network shares openHABian will set up for you. The last important piece is viewing the logs, till now the best option for that still is the ssh console.
Regarding DHCP: Nothing special here. If your device didn't receive an IP address somethings not right in your network.
Good luck and hope to see you in the community forum soon!
