If i may suggest:
Draw up a simple and cohesive plan first.
Then do & track.
Then revisit your plans VS yr tracking results.
Tweak yr plans and do, & track
Rinse & repeat.
BTW, $70K is nothing to sneeze at. Congrats!
Personally, if i've saved up a lump sum like that and assuming all else is covered (buffer fund, insurance, etc.), i would:
a. Filter mutual equity funds to go into
b. Select 2 to 3 very different funds, with good returns for 10yrs (if possible), 5yrs & 3yrs
eg. PFES, PRSEC & PFEPRF if U want to use cash for foreign mixed which i do.
EPF is used for local mix like PIX, PSSF & PAGF
c. Take 50% of the sum, say $30K (i'm just example-ing here k, not exactly 50% of your $70k. Momma's boy can count

).
This $30K, i'd apportion to these 3 funds, eg. $10K each
Then, each fund, i'd stick to doing it for at least 3 years, thus that's $3,333.33 each year
I'd do the investment every 3 months (qtr), thus, that's $1,111.11 each period
Then comes the hard part - to do this using DCA or VCA or combination (TwinVest)? heheh - knowing me, i'd do TwinVest
See how it works out? That's JUST THE ENTRY PLAN example.U can leave yr $ allocated for these in cash OR put into Bond fund and then switch the value as needed every quarter.
BTW, the remainder i'll leave in Bond fund until i figure out what to do with it - most probably learn about REITs and then go after that

It's also stock market but much easier to understand and buy value.
EXIT PLAN example:When will i take profit or cut loss for mutual funds?
1. Take /lock in profits
I'd do this when there's super abnormal profits - eg. when i know statistically that returns on average for equity funds are about 7%pa to 10%pa, if any of my transaction hits like 20%pa to 25%pa OR like 50% to 60% in less than 1 year, i'd take some $ off the table
2. How much to take / lock-in profits?
All? 50%? 66.66%?
Me - i'd take the cost + expected profits off the table (switch back to Bond fund and await to be reused)
eg. cost +10%pa, and leave the abnormal profits to keep running if it keeps going up
at least i've gotten my expectations already AND those $ is still earning me % in Bond Funds
3. Cut loss
er.. i wont do this if i'm using Value Averaging or TwinVest. The risk is already mitigated (not entirely though) by putting in less $ when prices are high, thus unused capital is available to buy more when prices go down.
Whew.. sorry ar, long winded stuff. Just wanted to share.
MOIS - i think i've answered your Q here too 
Added on August 8, 2011, 9:08 pmMost probably REITs as in stock market's REITs. Real Estate Investment Trusts like BSDREIT, TWRREIT, AXIS, SUNREIT, etc.
PM's closest fund i think to a REITs fund is PFEPRF - Pub Far East Properties & Resorts Fund. Pls correct me if i'm mistaken / lalaland

Wow! this is what I am looking for... 'A ENTRY PLAN', the hardest part to understand is the 'TwinVest'... like a secret weapon used by sifu in the last moment of a kungfu show
Btw, during the every 3 months investment, do you recommend 'switch' to different funds or just apply DCA or VCA in bull/bear run? PIX (Public Index Fund), PSSF (Public Sector Select Fund) & PAGF (Public Aggressive Growth Fund)... all these funds are equity/aggressive funds (high equity ration/highr risk/high return)?
Thanks.
