Yes, this would be an additional assumption if the fin and the base are separate pieces. But often they are welded together and there is no resistance. 1 point bonus.

If you work out the problem but impose a convective heat transfer BC at the tip, then you can show that $L_c=L+t/2$. Maybe I'll ask you this question in the midterm..

I don't understand your question. The heat generation is $$ q=SV=SAL=S\pi r_i^2 L $$ because $A$ is the area within a circle of radius $r_i$.

Well no, because the rate of change of the energy is not always zero even if the matter is at rest. It can change because of heat transfer or heat generation.

I think it's better if you sleep over it and look again carefully into your logic and algebra tomorrow when your mind is more fresh..
