I'm with Pete on that - will only make them more suspicious of well documented applications if they think there is a free website taking people through every step and telling them how to make it look convincing - they will therefore treat every application with even more suspicion than they do now.
Pete - as for your application, I also don't think you've got much to worry about - it sounds like you're going to be providing plenty and know the sort of financial and accommodation info to provide - plus phone calls and visits and photos to evidence a genuine relationship. Just don't let them shake you or intimidate you.
The hardest part is for the filipina if she's called for interview - it is such an intimidating process for her, and unlike us, she's not used to regarding 'authority' with the same approach we are with out more westernised 'every one is equal' approach - filipinos don't like 'conflict' and don't like to contradict someone in authority - but she'll have to if the ECO puts a point to her and is expecting her to rebutt it to prove a genuine relationship/reason for wanting to go to england. Just give her plenty of coaching and above all convince her that she has nothing to fear from them - and not to be afraid of correcting and contradicting them when they go looking for any gaps in the relationship/application. Unlike in philippine business/relationships, the english ECO will expect and want her to contradict and correct him to prove a genuine relationship - filipinos think it is polite not to do this, but she'll need to get over that cultural norm - embassy officials do demonstrate a surprising lack of empathy for the cultural norms of their host country and do little to make allowances for it, even though they know full well that most filipinos will be quite intimidated by being interviewed by an english official in their second language.
But if you've got the evidence, he's likely to ask her less questions anyway, and provided she's got no nasty surprises lurking within the NSO (which I'm sure she wont have), then you should be fine.
