Ammendment to PHP code on part of my site

my website is www.mountpresent.com. please note the php code is very messy and is not optimised. An experienced PHP coder will be able to sort through the mess but it may take a bit longer. 1) Code needs to be added somewhere so that if someone accesss [login to view URL] (without the www) it still forwards to www.mountpresent.com. Currently the domain is on a different provider to the hosting 2) The homepage has a search box on it at the top When searching for e.g heart you see these results: [login to view URL] However the filter is not working properly or at all. It should work like the filter on [login to view URL] 3) [login to view URL] The gift guide filter should not show up on Step 3 The gift guide filter that shows up on the results page, is not working correctly and it should not look like it does. It should only give the options to filter by Budget or Category. 4) [login to view URL] There is normally a box to the right of the centre box in the above link. It is not showing at the moment as it is date specific, ie. only showing Recently Added products if there are any in the last two weeks. The issue is that as the browser window is reduced in width, the Recently Added box and the centre box move down to the next line. These boxes should not move at all.
