solve Joomla problems

Hi Joomla-experts, I want you to solve some problems for a website of mine([login to view URL]): - The ordering of article have to be automatically on alphabetical ordering instead of something else: [login to view URL] - At the right side of the menu-item 'tweedehands' have to be shown some modules, but they're not working right now. - When you look for companies in the search-module, you get the companies, but they don't link to the pages from the companies - I would like to install google-adsense for search (com_gsearh pro) - I would like to delete something in the menu 'bedrijvengids': Afbeelding Bedrijven Beschrijving Hits Een bedrijf vinden? Bekijk [login to view URL] ! 0 - I would like to have that readers can react at some newsmessages, but I don't want spam. Is there a module for that you can install very simple, without deleting the old news? - De vraag op [login to view URL] wil ik graag omzetten in actie, maar dat lukt me ook niet... - instead of 1 title of a newsarticle below the two newsarticles on the homepage I would like to have 3, as well as a solid no changing link to the newsarchive. - The menu's are shown without blank spaces in firefox. This has to be solved. It's peanuts for an expert of joomla, but as a beginner I'm just not that experienced. Make a good price!
