Solr search integration

Looking to integrate solr into Drupal. Trying to figure out a) how to update the solr updater for each node type submitted, edited and deleted b) how to develop a results page in Drupal that gathers the xml-based results (from a specific URL that generates the results) and displays them in a node. Two very different issues. Short term I can circumvent "A" while testing, but will be required in production so any short-term suggestions for "B" are greatly appreciated.
