This is extremely n00bish.. but I'm confused. Do I just point my miner like the website says..
It is very easy to start mining at P2Pmining. Just point your miner at:
http://p2pmining.com:9332 and use your Bitcoin address as your username. Use anything for your password.
Or do I need to download the p2p stuff and go through that stuff?
Yes, just like the website says and NO you don't need to download p2p stuff to use JayCoins p2pool.
To use p2pmining.com, follow your miners instructions for connecting to a pool.
For example, to connect using CGMiner:
cgminer -o http://p2pmining.com:9332 -u username -p password
Replace 'username' with your BTC address where the payments are to be sent.
