Take your time and read though the wiki.
I don't mean to sound like a tool, but its very straight forward if you take the time to read it and a minute to understand what it says.
For example this page
can answer the 2 questions you have left as best as anyone on this board can.
For the question: Will ps3 keyboard work with raspberry pi with no issues?
Click USB Keyboards on the contents table (right side).
Scroll down to Working then Sony.
Keyboard for PlayStation 2 (PS2) Linux. Works without powered hub with 5v1A supply, requires manual keyboard remapping with Debian Squeeze to USA 101-key layout.
Yes it doesn't directly answer if the newer PS3 keyboard will work, but taking a (now) educated guess; most likely will.
For the question: I have a Samsung sd card will this be compatable
Same page as before only this time click SD cards from the table.
Scroll down to Working then Samsung
8GB SDHC Class 6 (MB-SS8GAEU)
8GB SDHC Class 10 (MB-MP8GA, MB-SP8GA/EU, MB-SP8GA/AM)
16GB SDHC Class 6 (MB-SSAGAEU)
16GB SDHC Class 10 (MB-SPAGA aka MB-SPAGAEU)
32GB SDHC Class 10 (MB-SSBGA, MBSSBGVEOBGA-SH) fine with Debian Wheezy, but does not work with Debian Squeeze (debian6-19-04-2012: mmc0: timeout waiting for hardware interrupt).
Check your card and see if it matches.
Web browsing on the RasPi is a bit chunky at the moment and I'd stick to just using OpenELEC for video/music playing
