Answer 1

If you want to remove any field than use this,
<field name="website" position="replace"/>
you can remove fields which are from parent view. this is right way.
You can use these values in the position attribute:
inside (default): your values will be appended inside the tag
after: add the content after the tag
before: add the content before the tag
replace: replace the content of the tag.

Hope this would be helpful to you.

Answer 2

First add create the fields in *.py file and upgrade your custom module and later add the fields in *.xml and upgrade the module again,it will work perfectly fine.Now i can add the fields and hide the unwanted fields in my custom module
ex:I want add Mothername and Father name below "JObPostion" and to hide website field
the below is the working code
My code
lead_view.xml
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<!-- ===================== This is tree layout =============================-->
<record id="lead_tree" model="ir.ui.view">
<field name="name">Lead</field>
<field name="model">res.partner</field>
<field name="arch" type="xml">
<tree string="lead">
<field name = "name"/>
</tree>
</field>
</record>
<!-- ========================This is Form layout===============================-->
<record id="view_res_partner_inherited" model="ir.ui.view">
<field name="name">view.res.partner.inherited</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_form" />
<field name="arch" type="xml">
<data>
<field name="website" position="replace"/>
<field name="function" position="after">
<field name="mothername"/>
<field name="fathername"/>
</field>
</data>
</field>
</record>
<!-- ========================= Action Layout ============================= -->
<record id="action_lead" model="ir.actions.act_window">
<field name="name">Lead</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">res.partner</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
<field name="view_id" ref="lead_tree"/>
</record>
<!-- ===========================Menu Settings=========================== -->
<menuitem name = "Lead" id = "menu_lis_lab" action="action_lead"/>
</data>
</openerp>
and
lead.py
from osv import osv
from osv import fields
class res_partner(osv.osv):
_inherit = "res.partner"
_description = "adding fields to res.partner"
_columns = {
'mothername': fields.char('Mother Name',size=64,required=True),
'fathername': fields.char('Father Name',size=64,required=True)
}
