Which Web Design & hosting service is best for me?

I'm looking at starting up a little e-commerce buisness. With these components:

1) A free area with news feeds that people can subscribe for free. I should be able to do this fairly simply using a blog/rss feed system.

2) A storefront where people can purchase doc pdf and ppt files. Ideally they make their payment through Paypal and then recieve a unique link or the file via e-mail. I have NO IDEA how to go about this part. I understand paypal and the e-commerce connection, but what about triggering an automatic e-mail that delivers the purchased product?

3)I don't need anything fancy as far as site design. I am horrible at designing my own site (I do not have an eye for beauty or ease of use!) so I just want a clean template where the above parts can work together.

So, what hosts would you recommend and what should I make sure they offer (besides the basics of 99.9% uptime, ect)? If this has already been answered in the above posts, just point me to them, I couldn't find anything.

Thanks for your help!
