To add on to shuttergal, if, however, everything elase is perfect, I'd go for repair since you won't be "wasting" one body, and you spend less than you would a 2nd hand one in decent condition. At least you know whatever you repaired is almost good as new, depending on the quality of your repair service.
The one at Sunshine Plaza is called Camera Hospital, if I'm not wrong. Never stepped in before but passed by it a number of times. Another place to get repair quotations for free, and probably good prices should you decide to repair, would be P&G at The Adelphi, opposite Funan Centre. There's also a branch in Peninsula if I'm not wrong.
With regards to lenses, I'd do some research and see if the lenses can be used on other cameras anot, or stick to the one you already have, or get just a few lenses to cover the range you'd most likely shoot in. You should determine if the money spent on the lenses and the repairs is worth the amount you're shooting. Otherwise, IF there's no sentimental value, then I guess you could just display it or sell it.
