A lot of what helpdesk [or helldesk], in companies and government departments at least, do is go remote onto someone's computer and see what's wrong, mainly because there's a lot of people with just basic computer skills [i.e. they know how to turn it on, they know how to surf the web and they can use some word processing programs, but that's about it]. The reason why there's lots of phone contact as well is because it's usually quicker for people to call up and explain their problem, instead of writing an email and waiting for a response. It's also quicker for the helldesk person because they can discuss and deal with the problem directly. Although there are people who email their issues, if their issues aren't pressing.
I used to visit the helldesk people regularly at the last place I was working at, because I was to train them in doing a certain task...didn't envy their job in the slightest.
Web design and web development can be quite interesting, although unless you are working for a company where someone else is supposed to handle client requests, then you'll also be making lots of client contact. It's mainly because you need to make sure your work is progressing in the way that your client wants. There's no point making a website that's deemed unsuitable by a client, and having to rework everything.
I think nowadays, to be a web designer, you'd need good graphics skills as well as knowledge in HTML, CSS, PHP, Javascript and maybe ASP. Apparently they're not hard languages to learn, although I never really got past Javascript myself When I was doing it, it was okay just to get by with HTML and CSS knowledge.
