Sounds like you're off to a good start. There are plenty of people who take a lot of pride in the brand name they are playing. And no doubt about it, some manufacturers like Hogan, MacGregor, Titleist and Mizuno produce some great looking sticks.
The truth is however, that the fit of the clubs is much more important than the brand or even the style. Clubs that are too short, too flat, too light or heavy or a shaft that is too whippy or too stiff will make it very hard to learn the game. If money is a consideration, I think you will be far better off getting custom made component clubs, or getting second hand clubs, and spending the saved dough on lessons.
It's a lot easier to learn how to swing correctly from the getgo rather than develop some bad habits and have to correct them later.
As for setting up the clubs, I think you're pretty close. A young athletic guy your size should definitely go with stiff shafts. Remember that one manufacturer's stiff is another's regular however, as most guys like to play "stiffs" to feel manly and the manufacturers have tried to make them happy. So the shaft manufacturers have gradually made stiffs into what used to be a regular. Aclubmaker can frequency measure your shafts and get them just right. Also, the longer a shaft is the more flexible, so your long shafts will play lighter than a regular length shaft of the same stiffness.
As for length, I would consider tapering your irons. Make the short clubs the full 1 1/2 over, make the middle irons maybe 1 inch over, and play the longer irons, which are hard to hit already at maybe 1/2 or 3/4 over. They will still be plenty long. Make sure you get an upright lie angle. A regular lie will probably have you hitting the toe first, which will ruin your shots. A clubmaker can measure you for the proper lie angle, and also make sure your setup and posture are decent.
Good luck and keep it in the short grass.
