I'm the aforementioned druid in Kal's campaign.  It sounds like you are debating between a blaster druid (like me) or a summoning druid.  I'd say pick one of those and choose your feats after the fact.  If you want to be a summoner, than absolutely take Augment Summoning.  It works on all your summons, all the time.  The Sudden Metamagic feats only work once per day, and personally at least I don't like that limitation as a summoner.  As a blaster, however, its alright.  However, I'd have to agree with Kalendraf the the Spell Focus and GSF feats are what you'd probably want to hone in on first, choosing Evocation.  As stated earlier, Natural Spell is a must have.
I don't want to devolve into flaming or anything, and besides such a conversation would be more appropriate in Rules, but I completely disagree with your take on Natural Spell Saeviomagy. Your post comes off as needlessly snarky as well, in my opinion. Natural Spell doesn't double as Still and Silent Spell, however how is the Bad Guy supposed to know if that squirrel is chittering angrily or casting a flamestrike? There are certainly ways to determine if a wildshaped druid is about (detect magic, knowledge nature, ad nauseum), but I really don't think the druid needs to make any sort of a bluff, move silent, or whatever kind of skill role to "hide" his casting. However, YMMV.

		 But, if you really want the Track feat anyway, I will make a pitch for adding a Ranger level...  (I get the impression that you are creating a CR5 character to start, otherwise, this will make no sense..!)  If you go Ranger1, then straight Druid, you will give up a caster level- but in exchange, you will effectively get a 'free' feat (which might be one of the 'blaster' feats...) and loads of skill points- WAY more than if you went straight Druid.  Your BAB will be one better, and HD the same.  If you want to sacrifice another level later on, of course, you could pick up a Combat Style, to boot.
