Really?
That's something I'd really like to see changed. Although I prefer to stay Premium status and purchase everything in the game instead of going VIP, I would like to see our VIPs have access to all (or at least some) of the purchasable storage while they remain VIP. That's such a quality-of-life improvement in the game, especially when TR'ing and working with the TR cache, that it would be a huge incentive for people to become VIP.
Welcome to the game, and congratulations on finding a Portable Hole! Be sure to check out some House Kundarak quests to unlock a character bank slot or two!
For tools, people generally don't use the healer/repair kits anymore. Players generally max their UMD skill to use wands and scrolls or have hirelings. Long ago, thieves tools only stacked 50 in each inventory slot, but were changed to now stack 1000 of them into a single inventory slot. That was a huge help for tool storage. A spell components bag would be a major help, though - as long as the game could access those items while they're in the bag.
Potion and wand bags would be really nice to store spare potions and wands when you don't immediately need them. However, if players need quick access to any potion or wand while questing, they put them into a hotbar to click on. Having them inside of a bag would likely prevent that ability. I'd personally like a wand bag, since I might want to carry a few wands of Blur, Shield, and Protection from Elements; and I'd only need one of each in inventory. A bag would keep the spare wands organized.
Great job on finding the quivers and bags! Those tend to be difficult for new players to find. When you start crafting, doing Shroud raids, participating in certain festival events, or hit level 20 and start looting epic crafting ingredients; you'll appreciate the larger ingredients bag. Once you start doing a lot of the quests outside of the Harbor and Marketplace or do certain other festival events, you'll be overflowing both of your collectibles bags on a regular basis. If you do Cannith Crafting, you'll need to hang onto those collectibles. (Players will buy and trade those collectibles from you at a much better price than NPCs would pay you, if you ever need to get rid of some to make space.)
Solving some of the inventory issues with additional types of specialized bags would be nice, and would keep all of each type of item neatly organized; but I'm unsure of how difficult it would be to implement since it might create some really weird gameplay bugs. It would probably be easier to increase the size of each storage tab by five, or perhaps add another bank tab accessible through House K favor. At the very least, VIPs should have automatic access to additional storage, since they're paying SSG's bills each month.
