Do some changes on a wrodpress website

Hello. I got a wordpress website, and i need some mini changes to be made on it. Website: [login to view URL] 1. I want the text of the excerpt of the articles to be shown better at the home page. now its shown in a mess.. there is so much spacing between the words, this must be fixed. Also image of the articles at the index page should turn 50% bigger. (both width+height) 2. In some excerpts, the title isn't showned good as well, you can check the screenshots attached to see what i mean. i want this to be fixed as well 3. there are two lines that is seperating the lines of the articles, i want this to be changed to a more thin line and a continious one, not a dashed as it is now.. 4. At the facebook-comments plugin, i want the colour to be changed. where most light white is, to be changed to cyan 5. if i move to "go previous" at the index page, it goes me to /page2.. there, there the black background is missing, and i suppose and if i go even more back the same story, this must be fixed. Photos are attached. PS: No milestones will be added, fully payment after.
