On the contrary, less data = better performance. But maybe you want to rebuild your indexes.

Is the ID the Primary Key Field?

that's not a clear answer to my question. but....
if the ID filed is Primary Key in one table and Foreign Key in other table. Create an index on that foreign key too

As Tomas mentioned, no it is not a problem. You should have a regular maintenance sql job plan running and part of that should be rebuilding indexes so there should be no issue.
