Hi!
LFO stands for Low Frequency Oscillator. It is usually used for vibrato FX (mild amounts of pitch modulation) but it can also be used to modulate other synth parameters. A filter for example. Or Amplitude. Or whatever a synth lets you.

4 voice polyphony means you can only play 4 notes at a time. Expanding on this Monophonic means you can only play a single note at a time (usually great for leads and bases and is referred to "Mono" or "Solo" KB mode). Polyphonic on the other hand means that you can play more than one note (the amount usually depends on the synth. My Motif ES does 128 notes polyphony for example. Yamaha VL-1 on the other hand can only play maximum of 2 notes).

Patching means connecting multiple devices or modules with cables. Coms from the old days of modular analog synthesizers. back then synthesizer programming involved connecting multiple modules (components of the modular system). making connections was referred to as "Patching" and the resulting sounds were called "patches".. Virtual patching on your Micro Korg or any other virtual analog synthesizer means virtually connecting multiple parameters and basically simulating a modular system of the past.

Before buying anything or going any further I'd advise you to learn as much as you can about synthesizers, MIDI and at least familiarize yourself with the basics. Without that step things will get very very frustrating and confusing. Do yourself a favor and Google for a bit. There is a ton to know and the more you know the more you will be able to do.
