Thanks for sharing your photos. The main subject of some photos were not in focus and this may be due to shallow DOF at f1.4. Try shooting at f4 to f8 to get the pinsharp focus of your main subject.
Maybe you can consider Olympus SP-570 or Panasonic Lumix DMC FZ18 for their long zoom range.
They seem to be great for outdoor shooting but performance of indoor shooting have mixed review.
Cheers,
