My first attempt at growing perennials from plugs - HELP

Renata, you have them on saucers, so water in the saucer, not into the pot. Let the compost become dry to the touch before watering or until the plants flag a bit. They're very small. The foxgloves are suffering from scorch so keep them out of the sun through the window. You'll know when to pot them on if you look at the underside if the pot and the white roots will be visible through the drainage holes. As for the astilbe keep it out of direct sunlight and again water in the saucer, not from above. Although they are all hardy they're far too small to go outside. You'll need to grow them on for about a month before they'll be large enough to go outside. The astilbe needs about another month as well. Keep them in indirect sunlight if you can and when you repot them next (at least a few weeks), pot into 9cm pots individually. By mid June you should have reasonability sized plants which you can harden off outside before planting into your garden. When you pot the carnations on pinch out the growing point which will give you more flowering stems. Don't hesitate to ask more questions there's plenty of free advice here.

Weed killer for new(ish) lawn

Leigh, spot treat them with that roundup gel stick. Although these products say you can treat a lawn after six months it's not at all wise. You usually leave it 12 months. The weeds you describe are probably plantains and they're easy to get rid of. You can hand weed those out.

Courgettes, tomatoes - container growing

Loopy if you're in central London your temps will be about 2 degrees higher than the surrounding counties, if you're in the outer boroughs you'll be at least a degree above surrounding counties. So base any planting out on forecast temps.

MChiz if you miss out pointing every second brick on the bottom level (side pointing), it allows excess water to drain.

Sue if you google slug resistant plants there's a list there, although I'd disagree with some suggestions. Wyevale garden centre and other suppliers are mentioned as well. It would be worth treating your soil with nematodes asap as it significantly reduces the slug population. That way it gives plants time to establish before the slugs can destroy them. Established plants fare far better than newly planted.

Hardy Geranium pruning

Kai, just remove the dead top growth, you can cut or pull it away and they'll get going with rising temps. After the first flush of flowers cut it all away again and you'll get another flush.

When should last years dahlias make an appearance?

C3k if they're outside its a bit early. Despite some nice weather the temps are up and down like a yo-yo. They need consistent warmth. If you bring them indoors for a few weeks they'll soon start onto growth.

Bird Poo

Something is roosting. Is it just general poo or have you had a good look at it. The only bird which roosts in the same spot consistently is an owl. A flock would spread when roosting so you wouldn't have a pile. Owls leave pellets rather than poo they regurgitate their waste. You don't live in west London by chance do you?

Well slugs and snails like them I'm growing free seeds from last year's GW mag. So far they're trouble free. Someone who grew them last year will be along so hopefully they'll give you more info.
