Greetings and welcome.
A great way to build your skills is to visit and watch experienced deacons. As you gain experience, you will be able to see all their mistakes
I am not sure of GLS has a book of workings - but ask about it. These, more than just ritual books, have a lot more detail on how to move in the lodge.
I became a proficient deacon by working as one in more than one lodge. I did not join them, but visited, and in announcing I was a deacon in my lodge, any DC or WM looking for a fillin might think of you if their number are thin. I spent years acting as inner guard for a daughter lodge of ours.. started when I was IG and sadly saw the Lodge pass its warrant in when I was WM of my mother lodge... but acting as IG sure gave me a lot of exposure.
One thing for sure - make sure you got to your own rehearsal, and ask if there is lodge of instruction or trainng lodge - or even better - a deacon school. There was a deacon school here, but it stopped running several years before I was initiated - but people still take about it, and you can often tell those who went as they moved around a lodge room with precision.
I would say over the years I've acted as deacon in not less than 6-7 lodges. Only ever been installed as one in my own mother lodge, but am often ready to answer the call to help. That's even seen me sit in the east as a visitor for a degree.
I guess this was all driven by being a bit of a perfectionist, and wanting to give the candidates they best experience they can get - you only ever get to do each degree once (well, there are exceptions - but that's a different thread!). I also aspired to become a ritual and ceremonial expert, and the best way to get there is by immersing yourself in ritual and ceremonial and a good way to do it is by helping out other lodges - it also gives you exposures to other Directors (or whatever title you might know them - the guys who run the degree on the floor). I was very fortunately to deacon for one of the best in the business, a great Past Grand Director who was DC at one of my two Craft Lodges. I ended up taking over from him.
Congrats on your investiture as deacon
