You don't say where you are sailing which can my influence this due to the size of the tidal range.
That said, if that was my slip and I was coming and going single-handed (which I do all the time), I would:
1) Back into the slip rather than go bow in.
2) I would have my spring lines on the opposite side of the boat from the finger of the dock (one less tripping hazard).
3) Since this is your permanent slip. I would have the spliced eye ends of the dock lines on the boat end of the line so you can quickly drop the eye on a cleat and not have to guess the length and tie a knot. [I would tie a clove hitch (with a double half hitch locker) on the pilings to reduce chafe.]
4) I would add hooks on any piling with a line tied to it to hang my dock lines. (The hooks should be on the front and backs of the pilings so that they do not hang into the slip or the fairway.)
5) I would get a boat hook that is easy to store in (or near) the cockpit.
6) I would do as Tempest suggests and add a line between the pilings away from the dock to keep from interlocking with the middle piling.
I suggest backing in for a variety of reasons.
- The Beneteau 331 backs and fills quite well and can be spun in its own length clockwise.
- (Once you learn how to do it) the 331 is actually more maneuverable in reverse than forward.
- Backing in allows you to grab the bow line and spring line while still in the cockpit. You can attach the spring line as you pass the piling and then walk forward with the bow line after that. The spring line will keep you from hitting the dock with your transom, and the pulling on the bow line then cleating it will prevent the bow from spinning towards the finger, and the stern from swinging away from the finger.
- If in doubt and need to bail out, forward thrust will stop the boat faster than reverse.
- Being able to cross the transom with the stern lines allows the boat to rise and fall a greater distance with the tide and lowers the force will increasing the stretch in the stern lines. This is especially helpful on boats with wide transoms like yours and mine.
For what it is worth, I have a very similar slip configuration to yours and personally (and with all due respect to my esteemed colleague) I love having pilings. They are much easier to tie reliable sturdy, chafe resistant knots on, and hang lines at a height at which you can retrieve them.

You might practice a bit to learn more about how the boat behaves. I typically will see how a boat operates in reverse and how it backs and fills near some marker so I begin to understand what I can and can't get away with. Once you felt comfortable with that you might try a few landings with someone on board as a 'safety' until you get to a point where you are more at ease with the choreography.
While off topic, while tying up in an area with a reasonably big tidal range but not extreme (2-3 feet), I like to tie my docklines at different heights on the pilings with lines on one side of the boat as high on the piling as possible and the other side roughly at deck level at a normal low tide, That way, as the boat rises and falls, one side tightens and the other loosens so that there is always a little slack in the lines.
Lastly, don't worry, you will figure this out. At some point you will wonder why it seemed so hard at first. We all go through this every time we operate a bigger boat than we are used to.
