Answer 1

You will need to write an extension class to support your customisations.

1/ For recordtype, you will need to get Opportunity.RecordTypeId , and then in your Visualforce page:

<apex:outputpanel rendered="{!recordtype=='whatever id'}">
<apex:pageblock table>
<!-- show all your columns -->

2/ To show "all" have an outputlink to a new visualforce page, pass the OpportunityId and display all line items on that page

3/ Use this enhancer for your sorting - its very useful.

4/ Cannot tell why your delete doesn't work, is the line item already deleted?
