I did print out the starting hands chart (for some reason it works better for me in grayscale) and used it for about 100 hands of single-tabling 2NL on Party. At first I kept getting confused about suited and unsuited hands but quickly grasped several principles that the basic preflop play article does not mention:
1) unsuited cards where the lowest card is weaker than T are never played
1a) unsuited aces less than AT are never played (bears mentioning separately)
2) connectors are not played unless low card is at least a 4
2a) unsuited connectors lower than JT are never played (bears mentioning separately)
3) in early and middle position you play only pp and AK
I made a couple of errors getting confused whether my cards were suited or not but cleared up that problem by switching to a four-color deck.
I had some issues figuring out bet sizing but eventually settled on counting the actions as they went around the table: "Fold so still raise 8 cents, call so raise 10 cents, fold so still 10, fold so still 10, call so raise 12" and so on. It worked well when I did it out loud (but would probably be embarrassing if I were playing live

).
EDIT: I also found it helpful to say to myself when the cards were about to be dealt: "Okay, I'm now in MP2" or whatever position I happened to be. It prepared me nicely for reading the hand chart after my cards were visible.
During the session I had a VPIP of about 15 and a PFR of about 8. The curious thing is that I went to showdown only twice because the opponents kept folding to my raises. I also folded every single one of my blinds. But since the sample is so tiny I'm not going to pay much attention to them--or to the 49 leaks that Leak Buster found in my game lol.
After four-tabling badly for about 8K hands, I found single-tabling so relaxing that I think I could keep it up for 10 hours. I stopped playing this time only because the table died and I wanted to check the results. After about five sessions or so I'll try configuring the HEM HUD to see whether it helps.
I was VERY hampered by not having read the postflop play article yet. The preflop strategy was like gold, but postflop I sometimes found myself floundering. So I'm going to read the postflop play article before I practise the starting hands chart any more.
Incidentally, I asked about PokerStrategy's beginner playing system in the fora on both Cardschat and DragTheBar but people are being evasive. Nobody seems to want to talk about it. They're too busy screaming at me as to how PokerStrategy cuts off my rakeback. :p
