yeps, basically include ANYTHING that might "wow" the employer. specially the things that relate to that job. ABSOLUTELY anything ur PROUD of, don't worry of it sounding "silly". for example: i personally do a lot of performing arts, and i'm performing in the winter olympics in 2010. how do i put that in there? i can put it under volunteer or the closest to it's category and name it something super fancy and make it sound very professional. like "performer in the closing ceremony of the winter olympics" 

and make sure the less lines (written and table-lines) the better. short and sweet, at the same time informative. 

Don'r worry about how much you have done. 

i suggest you do the following:

Current:

Proper Job: include your tasks in this job in bullet points

Volunteer experience and other things you are doing now

Training: (put these in chronological order)

training one (date): tasks at training and skills learned

training two (date): tasks,

etc.

Past volunteer experiences or teaching or anything else that would give them an idea what you have been involved in

Skills:

computer

languages

etc

References

Maybe you can say that if they want them they can ask you for them.

Good luck
