No, you don't need to set on *INLR. Setting on *INLR controls the RPG cycle, but a linear-main module doesn't use the RPG cycle.

The linear-main procedure will just end when it gets to the end of the calculations. You _can_ set on *INLR if you want, but it won't do any of the cycle-related things like closing files.

Here is a comparison of a cycle-main module and a linear-main module.http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/index.jsp?topic=%2Frzasd%2Fsc09250802.htm

Conceptually, a linear-main module is much more like a NOMAIN module than it is like a cycle-main module. The only way it is similar to a cycle-main module is that it can be used as the program-entry module for a program.
