Glad I could be of help
Double clutching is not too hard, basically its the same as i described before except with a slight tap on the throttle in neutral. Doing it without the clutch is more difficult, and tough on the transmission, but for me it was worth it to really get a feel for how the engine and transmission work together. You don't really need to go to an isolated spot (unless you live in the city?) any time you've got a bit of distance between the car in front of you you can practice syncroed 3-4-3-4-3-4 shifts all day long.
Driving a with a 16 year old transmission that wasn't even strong enough for the engine when it was brand new and is probably the only bad component on the car... I learned to double clutch fairly quickly
