Key points
General information
This unofficial launcher is designed to be used in lieu of the game's built-in launcher (GRIM.EXE). Though it is not necessarily required (unless you are on a 64-bit machine), it does provide easy access to many hidden or undocumented features of the game, including the ability to run the game from the hard drive without inserting the discs, the ability to run the game in a window, the option to automatically load the last saved game, and several debug keys.
If you used bgbennyboy's unofficial installer, the launcher should be installed automatically. Otherwise, download it, and extract it to your Grim Fandango install folder. Then, launch the game using Grim Fandango Launcher.EXE.
Grim Fandango Launcher.EXE
Alternatively, you can copy the entire contents of both discs to a folder on your hard drive (skip any duplicate files). Then, enable developer mode (see the section below) and launch the game using GrimFandango.EXE. Note that if you do this, bgbennyboy's unofficial launcher may not function; running GrimFandango.EXE at least once may or may not resolve this. Also note that the aforementioned launcher is currently the only way to install the official 1.01 patch on 64-bit systems.
Yet another alternative is ResidualVM, a spin-off of the ScummVM project. Like ScummVM, it allows you to copy the game's contents into a folder and run the game via the program's launcher. To note, the team is still working out some kinks, since this is a custom and unofficial interpreter of the game's engine, so consider it a work-in-progress. With version 0.1.1, however, they have also managed to fix 14 bugs that were in the released version of the game back in 1998. Install simply requires the ResidualVM install and the necessary files from the game (detailed here) copied to any folder. Note that you do not run the installer of the patch, but rather place the patch executable into the folder.
If you have developer mode enabled, you can run the game in windowed mode. bgbennyboy's unofficial launcher includes a button to launch the game in windowed mode. Alternatively, there are two ways to manually run the game in windowed mode: either run GrimFandango.EXE with the -w command-line parameter, or open the in-game options menu with F1 and select "DIBSection Windowed Display" under "3D Hardware Options".

Notes
Grim Fandango has no main menu; it starts at the beginning of the game by default. You can load or save your game by pressing F1 to access the menu.
Running GrimFandango.EXE with the -s command-line parameter will automatically load the most recent saved game. bgbennyboy's unofficial launcher includes this as a toggleable option.
-s
Saved games are stored in the game's install folder and have a .gsv extension.
Enabling developer mode allows the game to be run without the discs inserted.
If you used bgbennyboy's unofficial installer, or installed the game by copying the contents of both discs to a folder on your hard drive, this is already set up. You can either launch the game using bgbennyboy's unofficial launcher, or manually enable developer mode and launch the game using GrimFandango.EXE.
If you installed the game using the official installer, and are using bgbennyboy's unofficial launcher, then open the launcher and click "Options" - "Run Grim from Hard Drive". This will copy the files for you. From there, you can launch the game either using the unofficial launcher or GrimFandango.EXE.
If you installed the game using the official installer, but are not using bgbennyboy's unofficial launcher, you will need to copy the entire contents of both discs to your Grim Fandango install folder (skip any duplicate files). Then, enable developer mode and launch the game using GrimFandango.EXE.
