You can mine Ethereum at https://vixice.com + dogecoins and litecoins. Ethereum is very interesting, but it seems like bitcoin is implementing the same technology, but this has still not been confirmed.
For forums I use https://bitcointalk.org/
If you want to see price trends, Bitcoinity is a very good site http://bitcoinity.org/markets/bitstamp/USD
For buying bitcoins I reccommend Bitstamp. https://www.bitstamp.net
This is the website I use for bitcoin related news (also other crypto currencies) https://cointelegraph.com/tags/bitcoin
You can use this website to create unlimited wallets: https://www.bitaddress.org
You can also find more “legit” sources for mining pools, both for BTC and ETH. But these are usually very expensive, and the profits are low. So you have to invest alot 10k+ USD.
