Answer 1

You can Reseed your table like this :

DBCC CHECKIDENT ('[YourTableName]', RESEED, 0);
GO

Answer 2

Well this is not a good idea if the id is associated with other tables it will make a big mess in your database, however I do not know in which context you want to use this so I leave it to your discretion. But instead of deleting you can disable the auto incrementer of the table in question, and write a bit to add the free ids. Obs; Continues to be a bad idea!
