Yep, know that feeling well...
Here's pretty much how I build motors. First, I pick a camshaft.
It may sound silly, but a lot of decissions are dictated by the cam, so instead of trying to figure out the best cam for the motor, pick the cam and build the motor around it.
The cam card will give you the rpm range, the amount of lift the heads will have to accomodate, and the basic purpose of the motor (mild, bracket racer, towing motor, nitro-fueled grenade, etc.)
Next, find a suitable block, rotating assembly, heads, and valvetrain parts that match up with the motors mission.
As mentioned previously, the aluminum vette heads are a pretty good deal for a mild to moderate engine that needs to live on the street. They aren't sexy anymore, with so much more exotic stuff on the market, but they do function quite well, at a price that is quite reasonable compared to other heads.
Given what I think your motor's mission will be (a 350 street machine that makes the occassional trip to the strip for grins and giggles) then you will probably do well with a single carb in the 600cfm to 650cfm range. Realisticlly, you can make 300 hp and high two hundreds in torque without breaking parts, or having to resort to robbing the local 7-11 for gas money.
BTW, have you taken a peek at the axle code on you car yet..to see what sort of gears are in it? A lot of V6 cars came stock with 3 series gears...kinda extra bonus when you practically double the power output of the motor doing a swap.
