Choosing the right power regulator for Battery powered designs
Battery powered projects (particularly those with periodic events spaced quite a bit apart) usually benefit from using a linear regulator. Looking at your requirements (LiPo 4.2V to Vo + dropout voltage) a linear regulator will be (on average 3.7V battery, regulated output 3.0V) 81% efficient which is close to the SMPS solution anyway.

Smallest possible 3.3v regulator with Lip support for up to 320mA?
NCP1117 is a linear voltage regulator IC. That Sparkfun design is a complete module that uses MCP73831 which is a linear battery charger. Regulator regulates (and typically reduces) voltage, charger charges a battery, the two are not interchangeable! There is no such thing as "support for Lipo" in voltage regulators.
Can I just use resistors to drop the voltage or do I need some
For an application like this there''s no need to over do it with a voltage regulator or anything complex. The three AA batteries have an impedance of about half an ohm, giving 1.5 ohms when running off the AA batteries. The voltage of those batteries would be nominally 4.5 volts, a little lower than your power supply.

The Low Dropout Regulator
The low-dropout (LDO) regulator is an essential power management circuit in today''s systems on chip (SOCs).
