Suggested product for ticket support and project management

Hi there, please dont bite, but we are looking for an open source or commercial php product for ticket support and another for project managent. I have already googled a bit and what ive seen isnt so good. For our ticketing we mostly require a hosting style ticket system for server support and website problems with a tiny area for a bugzilla style code bug system. For the project management, possibly the most important thing is project logging, file sharing, reporting, calendar syndication and a possible integration with publishing and subscribing via ical. Its always possible to build it yourself but there is no time allocated to do so. Let me know thanks. Dan
