I agree, but I was making a point.
Ok. I don't quite see what it has to do with the question, tho.
If you have Practiced Spellcaster (twice for good measure), then you are a Wiz5/Sor4 with caster level 9/8. You obviously can only cast 3rd/2nd level spells.
This doesn't change the fact, however, that you cannot cast a 3rd level wizard spell with a caster level below 5.
You seem to confuse this part, that you need a minimum caster level to cast a spell with that caster level would be used to determine what spells a character can cast. These are two different things (and the latter one is false, too).
However, as I see it (after having thought about it a bit), this doesn't happen here (with the negative levels). If the character gains enough negative levels to lower the caster level to 3 (while still retaining 3rd level slots, not likely for the one with Practiced Spellcaster, but anyways

), then the 3rd level spell would still be cast at full caster level, but with a penalty to the effect, which reduces the effectively used caster level (for spell resistance checks, range, duration, effect, etc) to 3.
Obviously, it's arguable, but I believe that the CL is not modifed for purposes of reading the class table -- it's not a calculation or die roll.
That might be a valid argumentation. In general I agree with the conclusion, as said above.
