Old TV, new connections.

You could try what you have mentioned but you still may have issues. You didn't say what your TV has for hook ups, S video, VGA composite, etc. Also video aside, what about audio? Neither S Vid nor VGA carry audio. Some use a ROKU set up for similar purposes(with the internet) but it sounds unlikely that your TV is capable of doing such. The best hook up would require a total uprgrade of both L/T and TV utilizing HDMI hook ups that carry both audio and video signals, again a pretty heavy upgrade from what you are attempting to use.

You can do the connections, windows man, with what you have. All will be one way to the tv, or inputs. You can use the s-video and it will not hurt your computer--output is output. You must have a way to convert your video output from your computer to analog, either in the computer's DAC or use the DAC you have connected to the VCR. I assume your Apex converter has a rca (yellow) out for your vcr. The tv is not the main issue, it is making sure that you have an analog signal in video and audio to your vcr. Since you are using the headphone jack on the LT for audio, you can go directly to the vcr with your red and white connectors. Good luck, and do not forget that Thrift shops are now selling tv's with a variety of connector options starting at five bucks. RF adapters instead of the vcr are plentiful at thrift stores, and you do not have to have a power supply. Try Goodwill.
