If you always want to use data located in the same file, you must set this file as current workspace in ArcMap. In the Menu, go to Geoprocessing > Environment, Expand Workspace > select the file you want to use as a workspace. The workspace can also be a geodatabase. See Current Workspace (Environment setting) for more details about the current workspace and how to customize it.
This allows you to type only the basename of the dataset (e.g.: points.shp). The complete path to the data will be updated when you've finished typing (and click elsewhere). As @artwork mentions, if you click the browse button to select a dataset, you will land in the last browsed folder.
To set home directory, select Catalog Option button (in ArcMap)>Home Folder and browse for new home folder. Note for this update to take place you will have to close and re-open the application. Finally, open desired tool click parameter browse folder icon, and click the "Go To Home Folder" button and it will re-direct to the defined home directory. It seems that the "Go To Home Folder" button is only available in geoprocessing tools when opened within ArcMap.
