I recommend learning algs in bits, it makes the process a lot easier. Remember: It's a lot easier to remember four, 3-digit numbers, instead of a 12 digit number (unless you break it up into pieces).
The first 4 moves are a cake walk. If you don't have this trigger down, do it until you do (shouldn't take long). If you don't know the F perm, go ahead and take the above advice, and learn the 2 extra moves so that you learn 2 algs for the price of 1 type thing.
Personally, I do U' + y, but I kind of do a d' push with my right index finger. It still requires a regrip but a smaller one than doing a U' + y.
R' F' can be done two ways: F' with the thumb (like in T perm, probably the "common" or "standard" way to do it), or with an index finger push like Rowan uses (right index at RFU, pushes to UFL).
R2 U' R' U
R' F R F - Similar to Sledge hammer
Work on each of these bits individually, and put them together. Obviously the R' F' R2 U' R' U will flow really well, so put that bit together first. Really the hardest part will be the transition with the d'/U' + y, so it's up to you what to do with that, but find something that feels good and keep consistent with it.
Sub2 for all PLLs is a very achievable goal. If you set out to practice PLL by itself (say 1hr per day), you will quickly get all PLLs sub2. The way I recommend doing it: Pracitce one alg a lot of times, say 20+ times. Then you can move to a different PLL. It really helps to keep a log of where you stand with your PLLs, you can see which ones you need to work on that way.
Remember: Don't turn for TPS, turn for fewer lockups, TPS will come over time (it seems like obvious advice, but seeing/hearing it helps make you realize that you might be making the mistake). G perms especially need fewer lockups, it's easy to sub1.7 them after you get consistent w/o lockups and even a mediocre TPS (mediocre by normal standards, not by Feliks standards

).
