Problems with slider

Hi! I need help with slider settings. Problem N.1 I would like to put in the slider my pages with small text, but I get full text. And I get not only text but names of pictures or numbers of paginations as text in slider. Changes in Excerpt Length in Excerpt Options doesn't help. Even if "10" or even "1" are, in slider are to much words with another information. If on page picture is, then name of picture is in slider text, f.e. "IMG_001"... Problem N.2 In thumbnails under slider in your demo are all words in the middle and all it's ok. But my test page (i.e. the title) is left and down, not middle. Why? I reset all settings, nevertheless title is on this place - left-down. Problem N.3 If the title more 2-3 words is, this title is over thumbnail, because the font is to big and not changeable. Why is it so? What am I doing wrong? Thank you in advance for your answer.
