If you're really scared about your speaking score, I suggest to have it professionally evaluated. I'm quite confident in my speech, but even I got scared, because well IELTS is IELTS, and you never know: what's acceptable to you, might not be acceptable to the examiner. I only booked the exam when my online evaluator told me I'm good enough to get a band 8, which I did. I understand where you're coming, from a country such as ours, even though it is flooded in English, we always have an affinity for our native tongue; and believe me, having a professional tell you that you can get a 7 or 8 makes a whole lot of difference in your attitude towards the test. The bonus part about having someone evaluate you is that if they tell you that you only get a 5 or 6 now, they'll guide on what to do to get a 7. As least that's my experience from my chosen evaluator.
Nope, proof of funds is NOT a booster, but a minimum requirement which needs to be met; and they have strict requirements for it too. So you should build it up slowly and don't suddenly shock it with a huge deposit just before you create your EE profile, otherwise you might have a good amount of explaining to do if you ever get an ITA.
WES is not that complicated, it's practically the easiest of the requirement to meet: open a WES account, pay the fee, send the transcript, that's it and wait. They'll even provide you instructions on how to do it. The clincher part is when you say how they will assess you, and as I suggest in the previous message, they have a sort of preview option. Type in your school, and type in your degree and they'll pre-assess you free of charge. If you get a BS degree in the pre-assessment, go with WES, if not, then you can start looking for other options. I agree though, WES is expensive it's 220 CAD + shipping as I can remember.
I've actually read something like that too, and frankly I agree with it, since the LMIA process is something most companies in Canada would want to avoid; The LMIA carries a hefty fee for companies and can get quite lengthy to try and hire someone without a PR, so you can't blame them for choosing not to go for it. When I was taking one of the seminars/tutorials with British Council, I came across a fellow who said that it's his 3rd time taking IELTS not because he's not getting the band score he needs, but because his IELTS always gets expired for his EE profile and his immigration consultant can't seem to get him an LMIA job. If you do the math, IELTS has an expiry of 2 years, so if it's his 3rd time, then he's already been in the pool for at least 4 years. I don't mean to dishearten you, but unless you have a really niche skillset for a very specific position, I suggest that you shouldn't rely on an LMIA to get to Canada. Go for LMIA as Plan B or C, but not plan A.
You might want to go through the POEA route (the old school method for getting jobs outside of PH), then apply to Canada later for CEC, but that's something I personally would avoid, POEA can be a nightmare, so I've heard. Given you still have a few years to go before you turn 30, and you're really decided to Canada, I truly suggest that you look at the possibility of getting an MS or studying French, CELPIP is available here in the PH. At least you can control those factors, and can really help you with your immigration goals.
On the last bit, well you and me both, and I'm going to start losing points this year too because of age, so you can see just how much I share your sentiment especially with all of the recent events here.
