Welcome to WMT!
It depends on what your goal is. If it's to get one under your belt and make something drinkable, you picked a good kit for that. If you're looking for a meatier wine, then I'd add currants. While I know that folks have no problems doing it, the concept of cooking fruit before adding to wine doesn't compute for me.
One thought is to make this one as-is, then immediately start another kit -- either Classic + additives or Reserve. This gives you an early drinking wine and an opportunity for comparison.
Bulk age for 6 to 12 months, which is my advice for most reds. One thought is to get a 3 gallon carboy -- at the 6 month mark, fill it and bottle the remainder. This gives you a chance to taste your handiwork, while conducting an experiment in aging. Put aside 2 bottles, one to open 3 months after the remainder is bottled, and the other 6 to 9 months after that. Direct comparison is a great self-teaching tool.
I was taught to rack every 3 months, but have stopped. I rack only if I see benefit, and during bulk aging there is none. You will get fine lees, but that doesn't hurt the wine. Every time you rack you expose the wine to air and lose volume. Search the forum for "sur lie", we have several discussions on the topic.
Every 3 months I've been drawing off wine with a large thief, gently stirring in K-meta, and the re-adding the reserved wine. However, for glass and steel containers, there is a question if adding K-meta is necessary if the wine is undisturbed, so I'm re-evaluating that technique as well.
