Well you knew it was coming...I'm starting my IFR course work. Half trained, half skilled but wholly enthusiastic

Playing around with the I-1 last night and filing some other IFR flights previously.
1. ATIS tells me KSNA is landing NORTH so being a go getter I look up the north approach and uh oh...BACK COURSE LOC...so I lookup what that is and proud of myself for setting the inverse course into my HSI to get Right is Right and Left is Left sensing on the needle I move on
- I presume this is what everyone does?
- Any way to know which direction an APT is actually landing in PE? As in this case they weren't landing North despite the ATIS...would save a bit of hassle on briefing the wrong approach.
- What if you DO want to shoot an approach that's against the current landing direction - is that out of the question? And if so do you tell ATC you want "to circle", "the circling approach of LOC 02L?" - what's the phraseology and will tower tell you pattern directions for your circling? (phew)
2. Since I'm going to El Toro anyway (I figure) why not file ELB instead of SLI? So I do that too. (It wasn't for the rating fyi).
- The clearance came back the same SLI..I asked the CLR DEV guy about it and he says that the clearance is canned that way. Would this happen in real life?
2.5 What do you tell ATC if you want to practice multiple approaches? Do you tell tower for example you just want a "low approach" and then Direct SLI (or do you give them a heads up IF you intend to fly the Missed Approach ahead of time - and when?)
3. Standard clearances also came up when I filed a KRMN to KONT the other day. I had a nice single airway to PDZ and got surprised by a TEC route in return. Does Real ATC always assign TEC Routes despite what you ask? I came up the coast and through the "valley" near Chino. Does SOCAL actually keep people out of the E. side of the central valley? Or is that a PE idiosyncracy?
4. I've screwed up the "expect ILS-20R" vs "Cleared ILS-20R" a couple of times (alas)...Will ATC always tell you to expect Before Clearing you or can they just clear you (trying to mentally align the sequencing).
Thanks!
