If by loopholes, you mean in no way are you allowed to try to cheat the genie by giving him memory loss, summoning additional genies, or wishing for easy access to genie dimensions, you have to get creative.

Wish #1 “An indestructible tablet with inifite memory and power that can be summoned by myself when thinking about it, which is able to display any knowledge which can be known, provided it is true knowledge with as much information as will best benefit me, and created in such a way which is in full accordance with my intent, with no attempt to cheat me, and no drawbacks which can be introduced by any loopholes.”

The first wish is the most important wish because assuming I got the wording perfectly, you now have a source of infinite knowledge which can never break or fail, which displays all information which it is possible to know provided it is true. In theory, I could learn about the big bang, the end of the universe, the entire future of every stock, and most importantly, the genies rules against metawishing. In fact, I should be able to ask it whether there is any process by which I could attain more wishes, and such a vague answer could tell me all I need to know. But for the sake of the question, we will assume that all loopholes are closed.

Wish #2 “I wish that I have full control of my body in accordance with my intent, such that if I desire immortality, my biological body and DNA would adjust with no ill effects or drawbacks to such a state instantly and insuch a way that nothing bad could happen as a result of the wish but with no limitations on the extent, duration, or power of the ability.”

This wish is also important, because as with the previous one, if worded correctly, it is very powerful. If I want to become biologically immortal, then I become biologically immortal, with no ill effects and in complete accordance with what I want to happen, so that I don’t regress into youth. Similarly, I could become stronger, smarter, and faster merely by thinking about it.

For my third wish, I am going to wimp out and just ask the tablet from the first wish what I should wish for that would provide the most benefit to me. Really, the strategy is in asking for versatile gifts. The first one is the best, because it can do mind reading, precognition, objective facts, infinite knowledge, the most accurate Wikipedia version ever, infinite money, the best advice, key to political success, etc. Really, something like that would be what I would wish for. And the genie thinks wishing for more wishes is overpowered. I would show him overpowered.
