Questions from a beginner-ish

[weirdesky]

1:
I have an Eastsheen 4x4 that's real tight on about three sides. Would it be a good idea to lube it? If so, how would I go about lubing it?

2:
My DIY(a) cube comes apart (like... explodes) if I turn it too quickly. Is this normal, or should I tighten it in a big way?

3:
Is there somewhere I could find the XLL algorithms for the Ortega method?

4:
I'm really, really bad at look-ahead in F2L and in doing the cross. Should I just do them over and over again?

Sorry if they're dumb and/or posted elsewhere. When I searched, I either got a thousand and a half results or none.

1: Yes, put the straw of the lube in one of the sides an spray a little bit of lube.

2: Type a's pop a lot. Tighten the scews.

4. Practice going really slow, maybe 1 or 2 turns per second, and look at what's happening to the pieces. That will improve your look-ahead, and as you get better, you can go faster and still be able to look ahead.
