I think it's a dry granular product, right? My suggestion is sprinkle a handful lightly over each bed.
In the future should I not use this product nor any other organic fertilizer product?
I think that's entirely up to you. I think organic fertilizers have their place, when needed, but are not necessary to use by default especially if the soil is full of minerals, is healthy and teeming with microbial and fungal life. I believe what you're doing with the manure, compost and worm casting will set you well on your way to very healthy soil and purchased "fertilizers" will be unnecessary in the future. If I may offer a suggestion, consider adding a little unrefined sea salt, I use Sea-90, or kelp meal. These contain trace minerals such as yttrium, cobalt, iodine, selenium and others.
Is it better to say add 4" of fresh compost to each bed in subsequent seasons?
Yes. I believe compost and regular applications is always a good idea. It's an easy and cost effective way to add not only minerals but also abundant and healthy microbial life.
Is it okay to buy several bales of straw to help bulk up my compost piles? Say a bunch of straw and starbuck's coffee grounds? I could even break down the straw bales over the fall / winter by adding some 12-0-0 blood meal.
It depends. That's a lot of carbon, and the microbes that will break down and decay that straw need nitrogen to do their job, which the blood meal will help with. Worst case I can think of is it slows down the compost pile activity. I think coffee grounds are always a good idea. These things can make for a good compost pile. I myself would use straw over the surface of the raised beds as a mulch, and I've done this before. It arrests falling raindrops and prevents soil surface crusting, keeps the soil from drying out in the sun, keeps the soil from getting too hot, and provides
shelter for all sorts of soil insects, among other beneficial things. It will decay in place, feeding the soil food web and in turn also the plants grown in that soil.
Will that Jobe's fertilizer work fine for all vegetables?
yes.
each of the plants will take what it wants of the N-P-K?
Yes, with the aide of soil microbial and fungal life.
