Don't forget also that a VFR plan is really only a guide of your intended route. Because of the need to remain VFR you might not actually make it to the VRP or whatever. In any case, you are likely to be talking to an ATC unit at the points you mention and they will know where you are.
My recommendation is not to get too hung up on specifying every little point on a VFR plan. It does not get transmitted to units on route, so you will have to tell them anyway, and it is really of most use for SAR purposes, when a general search area is OK.
EGTB DCT SAM DCT MP DCT LFRC seems OK to me.
Remember that you are also supposed to put in an EET for the FIR boundary in the Remarks field.
