To solve this optimization problem, we first need to define the variables, objective function, and constraints based on the given information.

Let's denote:
- \(x_0\) as the number of blue highlighters,
- \(x_1\) as the number of staplers,
- \(x_2\) as the number of cafeteria chairs.

The objective function to maximize is: \(5x_0 + 8x_1 + 3x_2\).

The constraints are:
1. \(3.05x_0 + 0.11x_1 + 7.99x_2 \leq 67\) (total storage space),
2. \(0.11x_1 + 7.99x_2 \leq 61\) (storage space for staplers and cafeteria chairs),
3. \(3.05x_0 + 7.99x_2 \leq 22\) (storage space for blue highlighters and cafeteria chairs),
4. \(x_0, x_1, x_2 \geq 0\) (non-negativity),
5. \(x_0, x_1, x_2\) are integers (integer constraint).

However, upon closer inspection, we see that constraint 1 already implies the other storage space constraints (2, 3, and the total of 57 ft^2 mentioned seems to be a repetition or misinterpretation since 67 ft^2 is the total limit), so we focus on:
- The total storage space: \(3.05x_0 + 0.11x_1 + 7.99x_2 \leq 67\),
- And ensure \(x_0, x_1, x_2\) are non-negative integers.

Here is the Gurobi code to solve this problem:

```python
import gurobi

def solve_optimization_problem():
    # Create a new Gurobi model
    model = gurobi.Model()

    # Define variables
    x0 = model.addVar(name="blue_highlighters", vtype=gurobi.GRB.INTEGER)
    x1 = model.addVar(name="staplers", vtype=gurobi.GRB.INTEGER)
    x2 = model.addVar(name="cafeteria_chairs", vtype=gurobi.GRB.INTEGER)

    # Objective function: Maximize 5*x0 + 8*x1 + 3*x2
    model.setObjective(5*x0 + 8*x1 + 3*x2, gurobi.GRB.MAXIMIZE)

    # Constraints
    model.addConstr(3.05*x0 + 0.11*x1 + 7.99*x2 <= 67, name="storage_space")
    model.addConstr(x0 >= 0, name="x0_non_negative")
    model.addConstr(x1 >= 0, name="x1_non_negative")
    model.addConstr(x2 >= 0, name="x2_non_negative")

    # Additional constraints if strictly necessary can be added here, 
    # but given the problem statement, they seem redundant or less specific than the total

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
        print("Optimal solution found.")
        print(f"Blue highlighters: {x0.varValue}")
        print(f"Staplers: {x1.varValue}")
        print(f"Cafeteria chairs: {x2.varValue}")
        print(f"Objective: {model.objVal}")
    else:
        print("No optimal solution found.")

solve_optimization_problem()
```

This code sets up the optimization problem with Gurobi, solves it, and prints out the optimal values for the variables and the objective function if an optimal solution is found. If not, it indicates that no optimal solution was found.
