Go Daddy or Host Gator..............

Godaddy and Name cheap are registrars the people I know use, you most buy and renew with coupons on Godaddy to get competitive prices, the have quite an auction section for previously owned domains.

Hostgator is the most often recommended host, but that may be due to their high affiliate commissions to those who recruit new customers. I don't use them, but I'm not that sure my host is any better than hundreds of others.

Look through a few of the host review sites, just bear in mind they might get a commission for every host listed in their charts.
