Go for the 2nd hand route. I saw lots of good offers in Games Garage Sales.

If it's this easy to find used JP games...

Admittedly I haven't try looking at other places like eBay or even Facebook (don't even have account there lol). It'll nice if someone can bulk order used game from Japan, probably still be cheaper than new copies after shipping.

3DS screenshots may look terrible on a high-res screen especially when they're enlarged. But they look decent on the actual unit itself, especially when then 3D is turned on (even at the lowest level).

3DS games are region locked. You might be able to get games from eShop (not sure if local CC works), but the games for AU/ EU region are often delayed compared to US/ Asia.

Malaysia got the same region as US. You can get the one from official distro, or import from US if you want special versions. The later one you'll need to get local charger (or a cheap USB charger from Daiso)

Upgrading my SD card soon but I want to know if the card's speed do significantly affect game/ main menu performance. If it's not much I'll just stick with cheaper Class 4 card.

I read many conflicting statements on other sites so I prefer actual experiences please.

Maybe Daiso have some cheap replacement. If you want licensed stylus you can order from Play-Asia.

That one have no idea where to find. Most people either go cheap or go premium with styluses, but rarely the exact same one. XD

Just google or youtube top 3DS games and you'll get lots of selections. There's plenty of cheap good indie games too.

Not often but it usually during school holidays in US (or Japan if you're using JP eShop)

Yes you can. But any digital purchases on the console (if yoy have any) will be lost permanently.
