I can only go on my own (limited) experience. My first "real" open ocean dives were in the Gulf of Mexico and I was pretty "green" when I did them. Like you, I had gotten my OW and done a couple dozen dives, then gotten my AOW and dived a few times in Cozumel (NOT the same thing as open ocean, by the way). The Gulf was running a bit high for our type of operation when I went (3-6 foot swells, with currents ripping along at a pretty good pace. Sure, I made it fine, but I had trained for the occassion because in terms of diving experience I was the 'baby' of the boat. However, there were still others who struggled with the conditions and still others who made it but clearly weren't having too much fun.
In short, if conditions are favorable and all goes well, you should be fine. However, we're trained to be ready when things don't go as planned (and let me tell you, things can go south in a HURRY), and part of that training is honestly assessing your abilities and skills, then making the appropriate decision. For example, if you know you task load on "perfect" dives with good conditions, will you have the clearheadedness to call a dive if conditions turn rough? Only you can answer it.
As for the dives you mentioned, I defer to the wisedom of the experienced SB members ('cause I don't know a thing about them, except for what I've read, and that's a poor witness). I have complete faith that they'll guide you well.
