I like your second choice (the SP 'package') a bit better than your initial Cressi assortment. The BCD (Litehawk) would be a much better choice: back-inflate, moderate lift (~30lbs) appropriate for single cylinder diving, not much excess padding (which only adds to the weight you need to carry, etc.).
I don't really like 'package' deals, you often end up with gear that you don't really want, or which is marginal, simply because a vendor - online or local - wants to 'move' it. Your choice of reg brands should be based in no small part on what you can get serviced locally. Yes, in the states, some people even ship their regs off for service, and seem happy with that. But, it is not uncommon for regs to need some fine tuning after service (second stage adjustment), and that may be a bit easier to do if your service vendor is local. I don't know what your situation is. Personally, I do my own service, so the issue for me is parts kits. That is probably not applicable to you at this point.
The SP regs in that package are OK. They are on the lower end in performance, based on my experience (and it was NOT an issue of tuning). But, as part of the LP package, they are inexpensive. I do like the fact that both second stages - primary and alternate - are the same, rather than an adequate primary and a cheap, needlessly de-tuned alternate.
I agree with multiple posters about the console - don't bother. Get a PDC and use that for depth. Get a SPG (only). You will do fine.
The comments about the Zoop vs the Zoop Novo are useful. The Zoop is a D/C'd model. Frankly, if you can buy one - CHEAP - it isn't a bad computer. The Novo has a few more features, and is a better computer as a result, but it isn't altogether cheap. Still, it is a useful entry level PDC. I have dove Sunnto computers for 15+ years, and have had good success with them.
The fins are a more complicated issue. I dive open heel fins, warm water, cold water, and that is both my preference AND my recommendation - I dive from shore and from boats, and I like boots. For some diving I prefer heavy blades such as SP JetFins. For most of my single cylinder, recreational diving I use Mares Quattros, and have been using them for 15+ years as well (in fact, I had some stolen, along with other gear) and replaced them with the exact same model and color. They are great. I don't know why you 'hate' the XStreams, so there may be particular issues. I would not have purchased them, simply because they are more expensive than Quattros. (They are also heavier than Quattros and that may be part of your issue. ) Now, many newer divers experience at least some leg discomfort, even cramping, with virtually all fins, simply because a) they are not used to wearing fins (their leg muscles are not used to it), b) they try to fin WAY too fast and furious, and c) their finning technique is, shall we say, poor. I wouldn't buy a pair of splits yet, just because you experienced some initial discomfort with the XStreams. Use them a while, get your legs conditioned to finning, THEN decide what you might want. I have evaluated a number of pairs of splits, and don't use them. I don't get the propulsion efficiency I want, I can't back-fin easily in them, and I frankly wouldn't spend the money that vendors seem to want for them. That is just me. My overall advice is to wait a bit on a decision to replace your Xstreams.
If you go with the SP package, you will do fine. Frankly, the slightly lower-priced Zeagle package', that is shown just below the SP package on the LP page, is just as functional and slightly less expensive. But, you may not have any local shops that have Zeagle parts kits for the regs.
