What information do you memorize for verbs or adjectives?

[blackxlupin.livejournal.com]

Hi everyone,

I've been learning Russian for a few months now, and I'd like to start learning vocabulary more efficiently. I'd really appreciate input from more experienced learners/speakers on these questions:

1) Do you memorize the infinitive stem for every verb you learn so as to be able to form the past tense and the imperative?

2) When you learn adjectives, do you find it necessary or useful to memorize the short forms and/or comparatives (so you know which syllable is stressed)?

Thanks in advance!
