Hi Nugdam,
Fin forward will loosen the board up a bit.
I recommend getting the lessons sooner rather than later. You will be glad you did.
And you can join Sunshine Coast Stand Up Paddle Club on Facebook for free (great source of info) and to become an active member is $60 or $80 a year (and for that you get included in lots of comps and clinics and social paddles). They seem like a lovely bunch of people and I love their Facebook posts.
You will see from their posts where the good mellow spots are. They have a regular session at a local river mouth. I recommend it when the swell is smallish and the tide is running out just after high.
Have fun.
