First bho run. Experienced input PLEASE.

I just finished my first bho run and I'm pretty happy with the results. When I can get my PC on some Wi-Fi I'll post pics and full description of my process.
So anyway, I blew an ounce that was half trim and half bud. The trim was frosty and hairy, with some small bud chunks, from special k and purpleberry (grown very well). The bud was all last-phase hermaphrodite special k.
So far I've yielded three grams on the dot from two ten ounce cans of seven loop filtered butane. Does that sound right, or should I run another can through the tube?
As for my plans, I'm reserving two grams for edibles and one for a pg vape mix. Naturally I have questions for these two arenas...
Currently I use 14 grams of trim (like aforementioned) per six ounces of butter/24 Cookies. Using six ounces of coconut oil, how much of my bho would I use to produce a similar potency to my current recipe?
For the vape mix:
I understand that for vape pg mix one wants purity, and that it is obtained through vacuum purging or winterization. Since I currently do not have a vacuum rig, I'm attempting winterization. I added one gram of my bho to 3.5 ounces of 190 proof everclear, heated to dissolve, and put in my freezer. As I understand, I'm to leave it for 48 hrs, filter, and then I should be left with absolute amber, correct?
Once that is accomplished, I would mix in equal parts with pg and then it's ready to load into a cart?
Do I heat the mixture?
Any input into any of this would be very much appreciated :]
