Answer 1

Update: So it seems you need to get the first spelling suggestion from word. I checked this article and I deduce you would need to do something like this:

Word.SpellingSuggestions listOfSuggestions = 
                                  app.GetSpellingSuggestions(searchStr);
listOfSuggestions.Items[0].Name;//should contain the first suggestion

So from the msdn docs:

Syntax 1

expression.GetSpellingSuggestions(CustomDictionary, IgnoreUppercase, 
    MainDictionary, SuggestionMode, CustomDictionary2  CustomDictionary10)

Result: Returns a SpellingSuggestions collection that represents the words suggested as spelling replacements for the first word in the specified range.

Syntax 2

expression.GetSpellingSuggestions(Word, CustomDictionary, IgnoreUppercase,
 MainDictionary, SuggestionMode, CustomDictionary2  CustomDictionary10)

Result:Returns a SpellingSuggestions collection that represents the words suggested as spelling replacements for a given word.

Note: If you use anything earlier than .NET4 then you'll have to use Missing.Value for the parameters you want empty/null. As of .NET4 we've got optional parameters and when you add a reference to the Office Library, the interop wrapper will have overloads based on the optional parameters.
