does having to large a rear tire help to create under steer in my car

2. A friend has a roadster with a 275F/ 315R combo and it understeers. My guess is yours will be worse with the 335's in back. Based on this a front bar will only make the push worse. Hence a big bar in back will probably be needed. Some push can be dialed out with more camber in front....say -2 to start with, and less camber in back.
3. If you have power steering then the sky is the limit on caster. I run 9 degrees.
4. Keep the oil pan above the bottom of the frame rails, and the current ride height is fine.
5. Don't jack with too much until you have autocrossed it a couple of times. Until you have explored the limits much of your cash may be wasted IE: a fancy front sway bar on a car that pushes.
Here is your guide: understeer / oversteer corrections
Hopefully others can fill in the blanks where I am lacking.
