It's nice that you newbies can support each other and celebrate small victories, like getting the heavy saddle up and on the back. There's just so much to learn! That's what makes horse riding a lifelong pursuit; you never learn it all.
If you have more specific questions, as they come along, it will be easier for me an others to give "tips".
In general, one tip I can give is to "mean what you say and say what you mean". If you ask the hrose to go, then get a go! Or else don't ask. If you ask for a trot, get a trot and don't stop asking until you get it.
BUT, don't be asking for things that your really don't want, like leaning forward too much and wondering why your horse is speeding up (cause you "asked" him to go faster). Or, thinking you want to go faster, but hauling back on the reins. Or, getting the horse to come to a stop, but still holding the reins tight.
So be very clear on what you are asking for, get it and then "shut up" (don't be noisy with rein or foot). Now, that's probably way down the line for a beginner, but it'sw something to think about, . . .
