Got a question, ever thought of adding Huntercoin to your merged mining options? The guy who developed MNC also help develop HUC its both sha256/scrypt merged mineable.
Huntercoin doesn't seem to make much sense to me. And namecoin can be bad enough. There's problems with the namecoin software. People complain that they want to mine bitcoin, not namecoin. Etc. etc. I sometimes wonder if having Namecoin is positive or negative for the pool. Yes, you earn a little more, but there are so many misunderstandings and technical issues. Not to mention every web wallet I have seen for namecoins are scams.
1. Can I stop mining at any time without losing all of my hard work?
Your work is registered in shifts and doesn't disappear no matter what you do. When a block is found the work in the last 10 completed shifts gets paid.
There is no "ramp up" in PPLNS. This is a confusing point of view that makes people misunderstand the way it works. See it from the point of view of the work in the shifts, not the blocks. If you just look at the blocks and how much you got for each one then you will only confuse yourself.
There's often one easy and one difficult way to look at the same thing. In our solar system the movements of the planets are easy to understand from the point of view of the sun. It's harder from the point of view of the Earth.
2. I see that I haven't earned even the smallest fraction of a bitcoin after 24 hours. Is this normal for 6ghz? I have 120,000 accepted proofs of work.
You get paid when blocks are found. Average time to find a block for us is around 41 hours now. Difficulty went up a lot lately. That's the average though - bitcoin mining is a bit like a lottery.
3. When I do see some earned bitcoins, is it going to be something like 0.00000001 or will the first posting be something like 0.00001000?
Depends on how much of the work in the latest (when we find the block) 10 shifts was done by you. If you have 1% of the pool hashrate, then you get 1% of the block income.
There is some info on payouts here:

It's bad luck. Average time to find a block 41 hours. Now we're at 144 hours. It happens. But luckily it can't rain every day.
