2 power points don’t really help much with manifesting
So power points are used to manifest psionic powers, e.g. with the psion class, but 2 more doesn’t make a huge difference. So the Wild Talent feat doesn’t really help very much with being a psion, nor does it really make a good reason, by itself, to multiclass into psion.
Mixing spellcasting and manifesting is hard
There is a prestige class, cerebremancer, that advances both spellcasting and psionic manifesting. However, like mystic theurge, it requires three levels in each class (to get 2nd-level spells and 2nd-level powers), like mystic theurge, it has zero other class features, and like mystic theurge, it only lasts 10 levels. Also like mystic theurge, cerebremancer is a trap. Getting some lower-level psion manifesting is not worth being three levels behind on your wizard spellcasting.
Unlike mystic theurge, cerebremancer doesn’t really open itself up to early entry tricks, at least not on the psionic side. A 1st-level wizard/3rd-level psion could qualify using Precocious Apprentice or any number of other tricks, which would be pretty decent, but there’s no option for reducing the number of psion levels. Since you already have eight wizard levels, that doesn’t really help you. The ardent class from Complete Psionic could get in with just two levels—use the Practiced Manifester feat from the same book to improve your manifester level and allow you to learn higher-level powers with your 2nd level—but it relies on Wisdom rather than Intelligence.
I did once write a revision to cerebremancer that has been well-received and always worked well at my tables. This addresses the pain of qualifying as well as the lack of class features. It also is homebrew, and further gives Dragon magazine feats as bonus feats, so it probably won’t be allowed at your table.
Finally, if you have the drow’s LA +2, and count as a 10th-level character, and are allied with and fighting against 10th-level characters, you are already pretty well behind the curve for a wizard. Unlike the mystic theurge I described in that answer, you don’t necessarily have an overabundance of power to spend on multiclassing.
A cheaper option: psionic feats
Having Wild Talent means you are a psionic character now, which means you qualify for psionic feats. Those don’t cost you XP or your spellcasting progression, which means they are vastly more affordable.
Unfortunately, there aren’t really a lot of psionic feats that are very useful for a wizard. Plenty are useful for warriors, and plenty are useful for manifesters, but not so much for spellcasters—and what options there are, are from Dragon.
Remember psionic focus
As a psionic creature, you can make a DC 20 Concentration check as a full-round action to gain psionic focus. You can then expend that focus in order to “take 15” on a Concentration check. Very, very useful for when, say, you absolutely must successfully cast a spell in a difficult situation.
Unfortunately, trying to become a manifester at 9th level—or worse, 11th—is a bit prohibitive from an optimization perspective. There also aren’t a lot of useful psionic feats for a spellcaster unless they are also a manifester. Ultimately, your Wild Talent is probably best used for psionic focus and that’s it.
