PF, you should definitely give it a try -- it's not at all difficult. I had a very nice chat with Jason at the recent Photographica show here and picked up a set of his whole plate-sized plates while I was here. Haven't shot them yet because I need to check the bellows on the Seneca WP camera I have, but hope to do so soon.
You do need to get plate-specific holders, though. I've been gathering them up for a while, either buying them at the show or on eBay (mostly on eBay) but you only need one to get started. They are almost just like wooden film holders, just slightly fatter. Rather than a flap at the bottom, they have a fixed bottom with a spring-loaded bar: you push the plate in against the bar which allows the other end to slip under the lip at the top. Have a look on eBay; there are generally a few around at any given time.
For development, I just use trays, although the Stearman Press guys just added 3D-printed plate holders for their small 4x5 developing tank if you've got one of those. But trays are easy enough. Some folks use Dektol to develop; I did at first, but these days have standardized on D76 1:1, which is what I use for film as well. I develop for about 10 minutes with the usual slight agitation for the first minute, and 10 secs of every minute thereafter. Then the usual stop-fix-wash routine, nothing special. Just be careful handling the plates, as the emulsion is fairly soft and can be scratched with a stray fingertip. Been a long time since I scratched one, though, so it's not that risky.
Two warnings on the holders: 1) they're wooden and old and not always well-treated. I have a bunch that need to be repaired, and its somewhat small, finicky work, which I've been putting off; try to find one in good repair, and 2) there are a few out there whose lock rib doesn't mate with "modern" cameras. Sometimes you can rig something, but it's generally easier to keep going until you find one that works, most of them do. I've had good luck with the Rochester Optical "Premo" holders. They're a bit small (can be hard to grab the handle for the dark slide; put a loop of tape on it to help) but work fine. If you get stuck finding a holder, let me know; I can lend you one.
P.S. FWIW, the plate holders often come with an insert that turns them into film holders. I generally just use film holders for that, but it's a possibility if you really don't want to carry much.
