The memory in DS211 is DDR3 (vs DDR2 in DS2111J). So regarding the hardware, apart from faster CPU also the memory is faster.

I guess a Synology distributor in your country should be able to get them for you. Unfortunatelly the licenses are IMHO really overpriced, e.g. Amazon sells them for ~60$ per 1 camera

There are also a few IP cameras that can save directly to a network share, so the Synology would then be used as a file server only. Even with higher camera cost, one saves 60$ per license so at the end it could be cheaper. There would be also no limit for number of cameras (other than network bandwidth and write performance, of course). In this solution the Surveillance Station wouldn't be used - which might be a disadvantage.
