Latest full version of Adobe Acrobat has some editing capabilies but can be patchy.
Try to open it in Adobe Illustrator, again can be flaky but may get the result you want.
Enfocus Pitstop is a plugin for Acrobat and is probably the best pdf edit software going around, but it is expensive and takes some time to get your head around it.
It really depends on the original software used to create the document and how it was turned into a pdf. Anything created in Illustrator or Indesign and exported to pdf from there can usually be edited with reasonably good results.
Anything from the likes of Publisher can be problematic at the best of times.
If none of that works, you could try placing the pdf into another program (such as Indesign) as a placed graphic and just covering over the areas that need editing with a new text box with the correct type.
Fonts can be a real issue. If you dont have access to the fonts in the document, most editing software will use a default font which can cause all sorts of reflow issues or text just dissappearing.
One of the original purposes of a pdf was to provide a file, that was cross platform and uneditable so as to provide integrity when sent to print. Of course, about 5 minutes after the creation of the very first pdf, someone was trying to crack into it and alter it.
