A great timely question. The answer to your question is, yes to all the above. That is, everything you have done and are doing and are contemplating, are really good, but it only makes sense in terms of "periodization." You say you've done a lot of cycling and climbing. You can think of these activities as anatomical adaptation during the off season. We are now in the preseason, which is the time frame in which you work on strength and muscular endurance. Devote all of October and the first two weeks of November to increased loads with specific exercises relatively focused on increasing strength and muscular endurance to your core and lower body. The target areas should focus on glutes, quads and hamstrings with squats, deadlifts, weighted lunges, TRX, ViPR, Swiss balls and various plank manuvers. Reduce the sets from 5 to 3 and increase the resistance. Between mid-November and mid-December, you can turn that increased strength into power and explosiveness with plyometrics. Don't be misled, plyos done properly put a very large stress on the muscles and connective tissues. Only pursue plyos after a gradual buildup of strength and stability up and down the axial skeleton. There is a lot of information available on plyometric exercise on the web. What I would recommend, however, is during this late fall power phase, start off with a variety of rubber medicine balls, 4, 6, 8 and 10 pounders. A couple of exercises would entail throwing a six pounder against a wall with a lot of torque through the hips, then catching it on the rebound while using its momentum to rewind the torso back into a cocked throwing position. Do each side unilaterally for 60-90 seconds. Give yourself a break for 60s, then go again. Take an 8-pounder, hold it with both hands between your legs, perform a deep squat, then extend as quickly as you can through the knees and hips to throw the ball as high as you can straight up in the air while jumping off the floor. Catch the ball AFTER the first bounce. Thiese are examples of plyometric activity that have a high intensity level, but are not as stressful on the knees and hips as say drop/land/jump off of an 18-inch box, or continuous box jumps on and off a 12- to 18-inch box. To summarize, high volume, low intensity (cycling, climbing) moves to higher intensity resistance exercise (strength training), then to power/speed training, which is very intense, short duration and combines speed and strength, along with agility, stability, balance and coordination. For skiers, I can't emphasize enough the need to strengthen the two primary abdominal stabilizers, the transverse abdominis and the lateral obliques, and the muscles of the posterior chain, the spinal erectors, gluteus maximus, medius and minimus, and the hamstrings. The muscles of the hamstrings, the biceps femoris, semimembranosus, and semitendinosus muscles originate on the ischium of the pelvis and insert below the knee, which makes them key agonists during hip extension, so important to performance skiing. Strongly developed muscles of the posterior chain are also good insurance in helping reduce the possibility of acl injury (especially among women). Another guiding principle to consider in your development is to focus on closed-kinetic chain exercise, through multiple anatomical planes using multiple as opposed to single joint activity. These kinds of activities usually demand less resistance as you focus on coordinating the different muscle groups involved in more complex mechanics. Following on, most of these "functional" exercises can be done while progressively adding instability to the base of support with the addition of Bosu balls, aeromats, dyna disks, etc. If you are really serious, you can also incorporate short-distance, high intensity hill sprints and/or track work up to 400 meters to really activate and load the hip extensors and quads, which act eccentrically to keep the lower body stabilized during the stance phase.
