The Amazon Echo supports many devices, and the list is growing every day. Amazon sends Echo owners an email weekly letting them know of new things to try. They also have a growing list on their website, which I can't link to for obvious reasons. Just know that Best Buy price matches if it's shipped and sold by Amazon, and you can go in to a store, play with it, get advice, walk out with it that day, and even have it setup for you by Geek Squad if you'd rather the professionals get it all setup.
As for the Hue lights in particular, they are supported by Amazon Echo, but you would need a Hue starter kit, as Hue bulbs require their own smart bridge to work. The bridge connects to your router and allows you to control the lights from anywhere, and you'll need to press the button on the bridge to allow the Echo to see the devices when first setting them up to be controlled by Alexa.
For some inspiration, CNET has their own smart home, which they've added a couple Echos to so they could control their garage doors, locks, etc with their voice. Do a search for CNET Smart Home on your favorite search engine.
Armed with that information, head to Best Buy and they can make recommendations on products that will do exactly what you want, and trust me, if you can dream it, you can do it nowadays with smart home devices. Just make sure you have a good router. Having an old router with a bunch of smart devices all talking to each other can really slow things down. You wouldn't want to tell your light to turn on and then wait ten minutes for it to do so. The latest 'Wave 2' routers are just coming to market, and they're designed for multiple device households with smart home and streaming in mind.
