Circuit analysis - determine the voltage and current on branches
A couple of tips:


The source is a current source. Therefore any elements placed in series with the source (R1 and L1) will have no effect on the rest of the circuit. They will affect the voltage the current source needs to produce to work. They won't affect the current through the two main branches.
R2 and R3 (and R5 and R6) are in series. You can combine them immediately to simplify your analysis.
This is the kind of problem where it might make more sense to just go to a simulator and get a numerical answer rather than mess around with the algebra to get an analytic result. (Even if you need an analytic answer, you can use a simulator to check your work very easily)
