I don't know anything about Mr. Cogliandro, but I am willing to assume that he is a good teacher.
If you pursue this, I would suggest you focus your AK training on what you do with Mr. Cogliandro, and disregard any videos.
My lineage in kenpo is Tracys, and I cannot comment on other lineages of kenpo. However, what seems apparent to me is that there is plenty of disagreement from one lineage to another, on how things are to be done. This isn't a Tracy vs. EPAK thing, but rather every single lineage that sprung from Mr. Parker, whether it's Planas, Wedlake, Chapel, White, Tatum, or any other. Largely from the discussions I've seen here and over on Kenpotalk, this has become rather clear to me. Mr. Parker taught many people over a long period of time, and what he was teaching changed greatly over the years. So what these different people learned from him depended largely on when they studied with him. And this has a great effect on what they themselves are now teaching. The result is that there really is no officially standardized and accepted way of doing any of it. So if you try and supplement your training with videos from Tatum of Planas or someone else, you could be trying to work with material that is directly in conflict with what you are learning from Mr. Cogliandro (I don't know what lineage Mr. Cogliandro is in, so there may be some connection there, but that's another issue and another possibility). Or at best, the material simply has no place in what you are otherwise learning. As a brown belt in SK, and a complete beginner in Parker Kenpo, you are absolutely not in a good position to be dealing with and sorting out conflicting information. If you were already an advanced Parker Kenpo practitioner, you may be able to get some benefit from experimenting with videos and seminars produced by other teachers. But at this stage in your training, you are not in a position to try and do that. To do so is most likely to be disastrous, a waste of your time and money and a great source of frustration. And the thing is, probably you won't even realize it until much later. You may go down this path for quite some time and feel confident that all is well and fine, and only later do you begin to realize that nothing really works quite right because you went about your training in the wrong way. By the time you figure this out, you've already wasted a huge deal of time and effort and possibly money.
I will echo a suggestion already put forth: continue your training in SK, at least to shodan, before you begin experimenting elsewhere. And to be honest, without a good instructor available locally, someone with whom you can meet and train with on a regular and ongoing basis, I still think you would be wasting your time to experiment with videos.
Just because two arts use the work "kenpo" or "kempo" to describe what they do, does not make them the same. They can really be very very different, and you absolutely do need a knowledgeable and skilled instructor to understand what you are doing. Watching a video and mimicking what you see is not the way to do it. I commend your enthusiasm and your desire to broaden your horizon, but really, videos are not the way to do it. Not for kenpo, not for any art. Your time will be much better spent if you focus on the training you can get with a good, local instructor.
