For the size of the harddisk you just have to add the amount of used+free: 97+77+1189+11 = 1374MB, so somewhere around 1.3GB.
And as for RAM: Showconfig says it all: 2.0 meg - this is standard for the Amiga 1200.
Finally, you have Kickstart 3.0. I suggest that you upgrade to 3.1 if you want to expand your Amiga a bit further.
The programs:
-CygnusEd is a text-editor, with lots of functions (ideal for programming in quite a few languages)
-MagicWB and MUI are Workbench-enhancers: you can tweak the looks of Workbench in a lot of ways using these 2 programs.
-XCopyPro is a program to copy disks. Mostly used in the past for illegal copying of cracked games.
-Spectrum Emulator sounds like an emulator for Spectrum computers I presume :-)
However, if I were you I'd just format the harddrive and do a clean install of Workbench. You can get most of the programs from Aminet, or at least decent equivalents. This way you also get rid of a lot of (memory eating) junk that still might be on the harddisk...
