i've been using Chrome now nearly exclusively at work for about a month now and at home ever since I got my new computer ( I didn't even install FF on it)
There is a Web Developer Extension you can install (chrome doesn't have toolbars) -- it works just like the toolbar in FF (with a cleaner interface) but also has a couple limitations (like apparently no hotkeys, such as Ctrl+Shft+S to disable CSS). A few other features are missing too - like "view generated source" BUT they can be found through Chrome's very nice firebug-like "Tools > Developer Tools" window which is really helpful and comes standard.
Speaking off firebug, there is a firebug "lite" extension too but I haven't installed it because, again, the Developers Tools window is super powerful.
I'm not sure if there are comparable extensions for your other listed plugins, but I wouldn't be surprised if there are. I've had good luck adding extensions. One of my favorites is Google's "Personal Block List" that lets you weed out spam-farms that show up in your search results. You can block sites like devcomments from showing up!
The reason I've been running it at work is because for somereason FF was crashing on a daily basis (on my <1 yr old macbook pro) mostly because I had a dozen tabs open and run Pandora. No problems in Chrome yet.
Oh, and it "feels" snappier. At least, for javascript heavy sites like gmail and facebook.
