Hope you all are doing well

I have joined the Singapore Expats Forum just today.
I have applied for Singapore PR with my family and our appointment with ICA is in April 2015.
I need your advice on whether we stand any chance of getting approved. Sorry for the long post that is to follow.
Below are our details :
1. Male, Indian national, 31 years of age. Wife (30 years of age) and son (2 years).
2. Applying for PR for the first time. I will apply along with my family. I have been in Singapore since August 2010.
3. I am a Network Designer in a renowned telecommunications company. In my capacity as a Network Designer, I have designed the enterprise networks for several key sites for a major FMCG conglomerate in SEA. One of my projects has been inaugurated by the Hon. Singapore Prime Minister, Mr Lee Hsien Loong (Not sure if I can add this in the "Achievements" section on the PR Form 4A

4. EP-P1 pass holder with monthly salary of SGD 9.6K per month.
5. Masters in Information Technology from a renowned University in India.
6. Wife is Bachelors in Engineering (BE) in Computer Science from a renowned University in India.
7. Wife is in Singapore since December 2011 - but we haven't been able to find a job for her, so she is on a DP.
8. We have a 2 year old son.
9. We have been donating a fixed sum to Singapore Cancer Society (since March 2011 and still ongoing) and Singapore Heart Foundation (since June 2014 and still ongoing). Not sure if this helps either ? Sorry, I did not intend to put this here, but just need your expert views if this helps and should I state this on my covering letter to ICA ?
I would also like to confess that I did remit my savings to India previously until last year, since I wanted to buy my parents a flat, since they were staying in a rented accommodation in India due to financial problems back then.
However, at the moment, I have pulled in all my savings into my Singapore bank account (which is pretty reasonable) and do not intend to remit it back. Would it be worth stating this in my covering letter and be fully open and honest with the ICA ?
Thanks and looking forward to useful insights from you.
Thanks,
Rajdeep Joshi.
