Hello and I need some help!

I've entered chords for a song:

Verse 1 (Acoustic Guitar Only)
Chorus1 (Acoustic Guitar Only)
Verse 2 (Acoustic Guitar & Bass only)
Chorus 2 (all instruments join in - after a drum fill on beat 3 of the last measure of Verse 2)

Question #1
What I want to do is create a drum fill to begin on beat 3 of Verse 2...so, I have the drum fill to lead me into chorus 2. How do I enter this?

Question #2
How can I made the drum fill more interesting?

Question #3
How can I create a more interesting guitar solo for a couple of lines in the Chorus #2?


Any advice would be appreciated!

Thank you,
Paul
