The TLV parts are lower cost, lower performance versions of their TPS equivalents. So, there may be information on the TPS product page that also applies to the TLV version. In this case, this app note, http://focus.ti.com/lit/an/slva441/slva441.pdf, is highly relevant. It shows that the converter will be stable with 2.2uH inductors and an output cap of 10uF. A 22uF output cap is unstable. Keep in mind that this represents the entire capacitance on the output, not just what is shown on the TLV62065's page of the schematic.
Since this is a voltage mode converter, the MODE pin and load current have little effect on stability.
The app note and this one, http://focus.ti.com/lit/an/slva289/slva289.pdf, explain how to select the Cff. This should be done independently for each of their output voltages. They should also measure the stability/loop of their final circuit.
The 35kHz is the recommendation for the standard circuit with the recommended L and Cout. Since you are using a different L and Cout, you need to select the Cff empirically, per SLVA289 above. Smaller value resistors are just fine. The Cff may be much larger than 22pF commonly used.
