I like DuckDuckGo for search. Some say it isn't as good, but it gives me useful results, and has some niceties Google doesn't provide.
Give it a try for awhile, and see what you think. If you really don't like it, try StartPage. It's Google, but it's run through their servers first to anonymize your searches.
I use AdBlock+ with Fanboy's Ultimate list. That blocks ads, and much more...
I use Firefox. It's libre software, and I can view the source code if I choose. Aside from not liking Chrome much, I just can't trust a browser made by an ad company(Google). You like what you like though. You might also want to look into HTTPS Everywhere. It forces an encrypted connection when available, and will stop some referrer links from going through. It isn't perfect, and I occasionally run into a page that breaks when using it, but it's fairly rare, and easy to fix. You can either turn it off for the page load, or manually change the url to http from https.
