Outside of the ice baths, these should be staples of your lifestyle year round, but especially so when doing a high volume program such as this. Even more so as you age. Now, Plazma is great (I have to say that on this site), but there are certainly other products that can help you with recovery that are cheaper alternatives. They may not be equal to Plazma in content, but sufficient in effect.
Are you consuming intraworkout carbs? You don't need expensive complex carbs, just 40-60g of dextrose with some BCAAS would have a noticeable impact on recovery. Heck, if the BCAAs are too expensive, even just the dextrose or another source of simple carbs intraworkout would have some positive impact. It wouldn't be ideal, but it would help. If you're skimping your carb intake post workout then you should make it a point to increase that as well.
Your first priority really should be optimizing periworkout nutrition as best you can. If you have the time to add in the naps/extra sleep, that of course is always welcomed.
