Newbie playing FS2004 - help needed please

Hi

I picked up FS2004 and proceeded to do the first lessons etc - they went pretty well except I got annoyed when in a couple Rod ended the lesson cos I "appeared distracted?!", especially in the solo flight it was annoying because i was about to land. I'm having a few troubles:

Landings - despite completing the lesson, I find it difficult to land properly on the runway - any tips please?

Taxiing - no matter how hard I try gently upping the throttle and gently turning, I can never do this properly! I would like to do it even though I can still take-off half off the runway

Flight planning, heading indicator - despite when I make a flight plan when I create a new flight to embark on, the heading indicator seems to be random. Is there a way to set the heading indicator to my destination so I can just follow that all the way? It'd make it much easier for me as a newbie to practice short flights. Is there a software that can do this otherwise perhaps?

Are there any newbie easy to understand articles I can read to help me too as I'm clearly struggling? I read some of the ground lessons but the terminology is so complicated it expects you to be an aviation expert lol.

Finally, is FSX more newbie friendly and worth getting? 🙂

Many Thanks for your help in advance guys,
