Others have said this, but you really do need to get the main TIGHT otherwise reefing might seem like it is not doing much at all. Or making things worse! You need to figure out why you can't get the shape right if you're having problems here.
Seemed like your boom is higher than mine would be while reefing, maybe you need to pull on your boom-vang or cunningham a bit, or do you have a stop that is not working properly?
Also, you need to absolutely let out your topping lift. The mainsail should be the ONLY thing holding the boom up ... everything else should be pulling it down!
I don't mean that the trim has to be PERFECT, but when I first started experimenting with reefing I did not do a good job with sail shape. Boat would still heel like mad and I didn't understand why, until I focused on the shape of the main.
Also, you should always reef early, but sometimes you don't need to reef. I don't have a hard-set windspeed to reef, but I'd say it is around 15-20mph depending on gusts and other conditions that may impact control of the boat. However, I've found if the boat is just a bit too heeled, letting out the traveler does a lot.
When the main is properly trimmed this will twist and spill wind at the top of the sail: where it has the largest impact on knocking your boat around :)
Of course it is often that you should still put a reef in. Make sure you do this early, and get ready to reef before you even leave the slip, on very windy days. Can save you and your boat!
Also be careful of pulling on your stanchions like that. Sorry for being overly critical, but eventually you'll do bad things to the fiberglass and hardware and that is not a super fun job to fix :)
If you can find an experienced sailor to sail with you just once and show you his techniques for raising, trimming and lowering sails, your skills would take a quantum leap.
