If you're hell-bent on a Plus, then there's not much anybody can say to dissuade you. However, without a considerable amount of effort, a Plus will not go on the internet. There are people here who use them as web servers, but it's more of a novelty and to say, "Look what I can do with a 20-year-old computer!"
I don't use my Plus for anything besides exceedingly ancient programs that reside entirely on a single floppy (including the system software). I have Microsoft Works 1.0 or something for it, and I use that when I'm feeling particularly retro.
As for ClarisWorks, you probably won't be able to run anything higher than v2 on a Plus, and you'd need the external hard drive to store the installed program. If v4 works, however, I'd still be more apt to use v2 (or earlier). The only possible problem may be the fact that v2 won't open documents saved by v4. It's been a while since I've used any version of ClarisWorks, so there may be an option in higher versions to save a file in an older format, but I can't say for sure. This won't be a problem if you only have the one computer running it, though. As long as any files you transfer onto your Plus (via its 800k Mac-only floppy drive - don't try to use a PC-formatted disk) are in .txt or similar plain-text format, you shouldn't have a problem.
Like everybody else said, an SE/30 would probably be your best bet if you want 'net access. They've still got almost the same case, you know, unless you really don't like the horizontal lines on the later models. In addition, the SE/30 can read and write to PC floppies and use a Zip drive with no problems, plus they (usually) have internal hard drives that are greater than 20MB.
