CTR is your click through rate or clicks/impressions
That is exactly correct, although I sometimes find that a really basic example makes it even more clear:
So, if your ad appears 100 times for a keyword, you have 100 impressions. If you get one click, it means that one person has clicked on your ad, and gone to your site. And your CTR? In this case, it is 1 in 100, or a 1% CTR.

You should be able to find your ad by looking near the average position listed in your ad. If it says 9.6, it means that 9.6 is the average ad position for your ad, putting it near the end of the first page and possibly at the beginning of the second page. There are 10 ads per page, and since the position number is an AVERAGE, it means that the ad may be found a few spots higher or lower at any given time. If you had an ad that was at about 9.6 positionwise, i'd check the bottom of the first page and the top of the second page to see if it shows up.

Good advice. However, be sure you're looing at the average postion for a recent date range, such as 'today' or 'yesterday'. This can be very different than the average postion of 'all time' or 'last month'.
Also be aware that a low daily budget can prevent your ad from showing all the time. So you may not always be able to see your ad.
