Double Negative senior TD Erik Lehmann has shared 3 python scripts for Maya that can drastically optimize your workflow. The best thing here is that the scripts are free.
UV Tools lets you transfer UVs from one to several other objects and gives you the ability to quickly create and assign a UV checker map and add tiling.
With Selection Tools you can select geometry based on several conditions, including bad geometry, component count and groups.
Compact Renamer makes renaming objects easy providing options for adding a prefix, suffix, automatic serialization, padding, and a search / replace function.
