Sentence Correction (continued...)

First of all, before I post more questions that I need answered, I wanted to clarify a couple of things. These questions are problems about sentence correction and/or grammar that I do not understand. They are part of an Extra Credit Grammar Assignment in my Business Communication class. I am directing these questions to anyone that can help (i.e. not specifically teachers or students.) I'm sorry to have offended anybody or misplaced my question in my last thread. I have already fixed some parts of the sentences, that I believe needed to be fixed. However, feel free to let me know if I am correct.

*The number in parentheses denotes the # of mistakes according to the homework.

1. When we 1st arrived we attended a seminar on unique sales strategies. (2)
- The only problem I noticed was "1st." It should be written out as "first."
- I think the second problem is with the last three words. It should be capitalized, underlined, or italicized. I just don't know which.

2. The Seminar Topic was "How to Make Your Sales Calls Count". (4)
- "Seminar" should not be capitalized.
- "Topic" should not be capitalized.
- The third and fourth problems have to be with what is in quotations. I just don't know what it is.

3. The air conditioner in our Hotel room is to noisy, we can not sleep. (4)
- Hotel should not be capitalized.
- The comma after noisy should be changed to a period.
- "we" should be capitalized.
- ?

4. Neither Sherry or I plan to go to breakfast. Although, I enjoy breakfast more than any other meal. (3)
- "or should be changed to "nor."
- ?
- ?

5. Todays speaker is a world renowned marketing consultant. (2)
-"Todays" should be written as "Today's."
- ?

6. I also heard that Joe Manchin former Governor of WV . will be speaking (4)
- A comma should be placed after "Manchin."
- Period after "WV" should be changed to a comma.
- "will" should be capitalized.
- A period should placed after "speaking."

Thanks for help that can provided! It is very much appreciated!
