Hiya!
[MENTION=6704530]Saidoro[/MENTION], are you taking into account anything other than "in combat how effective would this be"? If you are, then ok, off you go.
If you aren't, then you are only half-way there.
For example, there is the whole "attunement" thing. That's a pretty big one. Also, if you rule that potions that duplicate spells follow the same Concentration restrictions; that makes a big difference. Additionally, say, the Broom of Flying; easy enough to just rule that when you are flying it, you need to have both hands firmly grasping it to control and steer it, and/or you need to Concentrate. POOF! No more casting spells with Concentration requirement, or Somatic requirements, no shooting bows, etc; basically, its a means of transportation. Period.
Of course, my "fixes" are only needed if it's a problem in a game to begin with. In my game, it's not. I think in the 10 (?) months we've been playing (me DM'ing every single game), my players have found a grand total of about 6 magic items. I think there was a cloak, a staff, a dagger, and a couple of potions. Lack of magic items hasn't made a lick of difference.
That said, I took a look at your price list. If you want to do the whole "Magick Shoppe" thing for your campaign, it looks like you at least have a good solid base price list that you are happy with. It is much more detailed than that in the DMG, so it should be easy for you to adjust as needed much easier. The only thing I'd look into is the spell-scrolls and potions; they seem a bit cheap, overall. A spellcaster being able to spend a few hundred (or thousand) gold to permanently increase his spell-count in his spellbook is a huge thing.
