Geth will acquire blocks in chunks of 256 (the first chunk can take minutes to appear). In the geth output, you will typically see low "txs" numbers and importing one block at a time when the block chain is synchronized.
With a web broswer, go to https://ethstats.net/ and look at "BEST BLOCK". Geth will be done downloading the block chain when your machine shows the "best block" number.
After the block chain is synchronized, end the geth process by pressing: ctrl-c

List the new account.
.\geth account list
Using geth console, verify there are zero rewards on the new account address.
.\geth console
web3.fromWei(eth.getBalance(eth.coinbase), "ether")
exit
Geth has now been downloaded, an account has been created, and the existing block chain has been downloaded.
The next step is to download the Ethereum miner.
