1. I had my 2 passport sized photos taken at CVS last week, but they did not have me take my glasses off. On the UKBA website, it only says no sunglasses, but I am worried about this. Has anyone ever sent their photos with glasses, and was it an issue? Should I just get new ones? Another one on the photos, they gave me 2x2 inch square photos, but the UKBA website says they should be 35mmx45mm. Will this be an issue? Should I crop them?
The photo size doesn't matter - they will accept 2x2 inch photos. You don't have to crop them.
Glasses are fine as long as they don't have glare or hide your eyes. They recommend that you don't wear glasses if possible, but it's not a problem if you do.
I've worn glasses for all of my UK passports except one and it's never been a problem.
In fact, with my latest passport, I didn't wear my glasses and when I travelled to the US, the immigration officer made me take my glasses off because he didn't recognise me with glasses, compared to the passport picture!
2. Is there any reason to include information about my current job/field of work? I am a social worker and I know this is a high demand field in the UK, so I thought it might make me seem more desirable. But if it isn't relevant and they won't look at it, I will leave it out. Just wondering what the consensus on that is.
No, they are not allowed to consider your income or your employment prospects for the visa, so there's not much point in including it.
They will only look at the UK citizen sponsor's employment and will ignore yours completely.
3. On Appendix 2 when it asks if you have ever lived together, we haven't, because we can't legall work and stay long term in each other's countries. I said something to this effect on appendix 2 as it asks for an explanation, but does this sound suspicious? I am trying to be very careful as it really is as simple as both of us having steady work in our respective countries, we were just married in December, and before that we weren't really eligible to live/work in the other country. Has anyone ever had an issue with this question?
No need to be careful - your reason is the same as many other people applying. It's normal not to have lived together yet and they will probably expect that you haven't done so before.
In fact, if you had lived together, this might cause suspicion, because UKBA would then question HOW you could have lived together if you didn't have a visa for the UK... they might then wonder if perhaps you were an illegal overstayer.
So, just say 'no' and for your reason: 'because we don't legally live in the same country, so haven't been able to live together yet' (or something to that affect).
