Yearly Maintenance for Tiger Cat

I bought a brand spanking new Tiger Cat 61" with a B&S engine last year...I am going to send it to the dealer next month for the yearly maintenance...it has 86 hours on it and the oil was changed at 5 hrs...I plan on having the oil and air filter changed, the blades sharpened and the fittings greased...is there anything else I should have them check/change...sorry for bothering you guys with this, but I am not very mechanically inclined...

Thanks/bg
