Sounds like a good setup and a comfortable ride, much the same as some of my boards in dimensions, along with many others on here too. My go to board is around the 8.5 size from Antihero, Real or Krooked with Jessup grip, Indy 149s, Spitfire 99 duro 56mm wheels, Bones swiss bearings, Shortys hardware. I have some boards with wheels down to 50 mm and others with thin risers and 60 mm wheels, but pretty much all the same everything else.
A couple of things (from a shop guy perspective) that may be of interest.
All normal Indy trucks come with 90 duro bushings, that are actually a way better product than what they once were, so in getting those you already have soft to medium bushings that will last and work really well for normal skating.
Bones bushings do break more easily than others, but they also do get softer over time, so depending on how tight or loose you want your trucks, I would say either skip the medium bushings (91 duro), or go for the Bones hard (96 duro) if you are wanting Bones bushings, only because 58mm wheels are going to give you a lot of wheelbite without risers, so slightly tighter trucks might be a better option for starting out, and then as the hard bushings wear in and soften up some, it might make it more comfortable for you to ride. Only if the Indy stock bushings are not what you are after though.
Get 1" deck bolts / hardware, not 7/8" as they will not fit comfortably unless they are Shortys 7/8" (which have lower nut height) which is what I use. With 1" you can still get thin risers on the board too, which might be helpful with big wheels, eg something like Bones 1/8" or Mini Logo .10" are perfect. Risers are not essential, but do help a bit, as well as being fairly easy to put on or take off too. You can always get these later too.
Bones wheels are one of the hardest and fastest, not to mention longest lasting and least likely to flatspot, on the market. The size 58 mm is definitely great for going fast and getting a better ride than small wheels, but the average of around 54 to 56 mm is more common. Also the duro being in the B rating is about the same as 101A, so yeah the hardest wheels on the market. If you were after something super hard and fast, they will definitely be a great wheel, but if you were after something not quite so hard, there are slightly softer options, around 97 duro just to take the edge off and not be quite so slippery, or 95 for decent grip. Anything below that, eg 90 duro is almost soft cruiser board wheel hardness, which is awesome for just rolling round having fun, but not so much if you want to skate nomally, do tricks, etc.
Spitfire has come a long way in 18 years too, now the Formula Four option is pretty much the go to for many people who were not so happy with the original formula, also very flatspot resistant and really good wheels, lots of shapes, sizes, also in 97, 99 and 101 duro too.
I think that is about it. There are a lot of great local shops out there who can give you good helpful advice, but it also comes down to whatever the shop has in stock, which is even more important if you are getting a complete and don't want to get some things from here and some from there.
At the end of the day, getting something that will be good to ride is more important than anything else and there are so many options out there nowdays it can almost be too much sometimes when looking at different places.
Good luck and I am always interested to hear or see what you end up getting.
