Questions & Answers about sekkaku hayaku okitano ni, densha ga okurete gakkarishimashita
せっかく adds the feeling that someone made a special effort, but that effort did not pay off.
So here it is not just I woke up early. It is more like:
- I went to the trouble of waking up early
- I woke up early for once / on purpose
- I made the effort to wake up early, but...
That is why it works so naturally with のに later in the sentence. Together, they create the feeling of I did all that, and yet...
Because 早く is the adverb form of the -i adjective 早い.
- 早い = early / fast
- 早く = early / quickly
Since it modifies the verb 起きた (woke up), you need the adverb form:
- 早く起きた = woke up early
Using 早い directly before the verb would be ungrammatical here.
