viix: Welcome! Man, where to begin? There's tons to cover

If you just search FPN, you'll find answers to several of your questions. Lots of S'poreans here

Are you looking for Italic nibs for your Safaris? Try Lin Kang on 3F Peninsula Plaza. $15 each. I suggest switching the nibs yourself, but they will switch them for you if you ask. It's just that the experience is... harrowing to watch
Or shell out for a Joy calligraphy set

If you're looking for more italic nibs, can try a Sheaffer NoNonsense calligraphy set. Available at the pen counter at many major department stores (seriously). Try Takashimaya 3F.
Ink: if you're just browsing, most of your ink needs should be met at one of the major pen shops here - Aesthetic Bay (2F, Funan), Fook Hing, Elephant & Coral (3F, Wheelock Pl). No-one stocks J Herbin ink here though =p
Paper: Can't go wrong with Clairefontaine paper. Rhodia uses them in their notebooks (not graph pads), which are widely available here. Try BooksActually. Some people here also like Japanese brands: Apica, Campus etc. There's a Japanese stationery shop in the basement of Raffles City. Can also browse the Stationery Superstore on 2F Funan. Moleskine paper tends to be too thin for fountain pens.
Pens: You already know Mustafa. Great prices but gotta know which pen you want.
Pen prices are high in stores for almost every brand of pen. You're probably better off ordering online, from Pen Gallery or pensinasia. The Sales thread on FPN is also a great place to browse

Almost every site will ship to Singapore. Just ask about cost first.

I remember and incredible dampness all around. It was difficult to breathe.... it's not an obstacle when writing? I would not recommend a Lamy 2K in Singapore!
LOL well, you kinda get used to the humidity after a while. I'm curious about your comment though - I have a Lamy 2000 and it works well here. But I've been told by an experienced repairman that the nib section will crack after 3 years and he thinks it's 'cos of the climate. Don't know whether to believe him @_@
Didn't you try the food at least?
