Hello all, I'm trying to get values at node for R3 and between R1 and R2. I know the voltage at through the LC is still going to be 9V. Also the Beta is 100. But if I dont have Ic or Ie how can I find either to solve for the base current?

Curious circuit topology. Is it meant to be an tuned (RF) amplifier or an oscillator? It looks rather like a common base RF oscillator.
One of the challenges with the oscillator option is determining what the bias conditions with oscillation will be - as distinct from the steady state non-oscillating or pre-oscillation bias conditions. If the circuit actually settles into something like class C mode (say) when oscillating, then a steady state class A mode bias analysis doesn't apply once oscillation commences & the circuit conditions stabilise.
But one can certainly analyse for the steady state (non-oscillating) bias condtions given the information you have at hand.
