Answer 1

can avoid enhanced grid default 10 rows size by this please check it

defaultPageSize: 50,.

use this in pagination plugin...

Answer 2

I think this might help you out: When you define your grid you can set autoHeight

I've copied this from dojo:

autoHeight

If true, automatically expand grid’s height to fit data. If numeric,
defines the maximum rows of data displayed (if the grid contains 
less than autoHeight rows, it will be shrunk).

For more informations have a look : http://dojotoolkit.org/reference-guide/1.7/dojox/grid/DataGrid.html#datagrid-options

Update1

Maybe this former Post makes it clearer: DataGrid's rowsPerPage attribute not working
