My list usually depends on the concept but it's always got these:
Epic Mage Armor
Greater Ruin
Epic Spell Focus
Great Fortitude
Mummy Dust
Mummy dust can be substituted with Dragon knight if you focus conjuration and prefer a pvp asset with more cited control factor, but you can also take it without the focus if you expect to win fights fast. It's great for nullifying the unprepared fighter because it has a fear aura, and I've even seen it beat other wizards who rolled the unlucky 1 because their saves were high and they got cocky.
Your DC doesn't matter that much because anyone who isn't prepared to beat a minimum of 39 on a fortitude save is usually going to lose, and if a dex build had the required fortitude they will also beat your reflex DC's. Will is to hard to buff effectively for non casters, so it's pretty reliable if they don't mindblank themselves.
You have a lot of spells that cannot be mitigated with savng throws, shoo use them liberally. They work great in most fights and you can always strip mindblanks away in a pinch with Mords.
Remember to always. prepare. timestop.
I've got my standard spread for my cookie cutter Wizard/ranger/Rogue below:
21 Epic Fortitude
24 Epic Spell: Mummy Dust
27 Epic Spell: Dragon Knight
30 Epic Spell: Hellball
Wiz 20 Great Intelligence
Wiz 23 Epic Skill Focus: Discipline
Wiz 26 Epic Sell: Epic Mage Armor
Ran 1 Epic Spell Focus
I'm terms of gear, you want lots of int/con/discipline/fort.
Epic Mage Armor will take care of AC so you don't need to worry about that (baring in mind that the Dodge AC from your boots stacks with epic mage armor stacks and is mandatory, and Epic Mage Armor does not account for your shield), and as a second level rogue you will have access to evasion. That means you free up a power slot on your ring finger and can stick MORE INT onto it.
You will also want to wear the care chain mail and shield that amia has so your ac can sit I'm the sixties where it belongs.
Also it's worth noting that I personally take my first wizard level in pre epic levels ago that I capitalize on having a bonus feat at level 20 to even out my int score with.
I'll pop back in if I remember more advice, but that's all I've got for now.
